So I went through some other files and it's blatantly obvious that one of two things happened. Either a) Bioware ran out of time to implement the ending they wanted or b) they're going to just replace this all with DLC.
I say this looking most specifically at Primarch Victus' dialog (below Admiral Raan). Victus' dialog shows pretty plainly that Bioware planned for your decisions in ME2 and ME3 to affect how the events on Palavan played out. If Wrex and Eve survived and the Genophage was cured, the Krogan and Turian allied together and essentially saved Palvan. If the alliance fell apart because Wrex was dead or Eve was dead or both then there were serious ramifications for Palavan and the Turians.
Now, based on some of the Geth dialog and some of Anderson's dialog it seems like there may have been a design around sending reinforcements to specific areas. Remember the map Anderson as using? There could be potential there for some sort of rock/paper/scissors gameplay there, sort of like the suicide mission in Mass Effect 2. I'll keep digging though the audio but holy ____ there are some implications in here. I'm... angry that this didn't make the final game.
Geth Prime
Shepard: Have the Reapers tried contacting you since Rannoch?
Prime: They made an attempt. We rejected it.
Shepard: Hope our guys haven't taken any shots at you.
Prime: Allied fire has been minimal.
Prime: Your military commanders briefed your soldiers extensively on Geth organic cooperation.
Shepard: How are you and the Quarians working together?
Prime: Geth platforms have been integrated with Creator Squadrons. We serve as front line uints.
Prime: It is a tactically sound strategy and there is (pause) synergy when we are in consensus.
Prime: Our hardware can withstand more damage than Quarian envirosuits and creators are skilled at providing cover fire.
Prime: We have coordinated with creator forces. Our platforms will support their ground units.
Shepard: What's your status?
Prime: Hostile outbreak suppressed. Self repair protocols engaged.
Prime: Hostile outbreak!
Prime: We are ready Shepard Commander.
Prime: Standing by.
Prime: Ready to join allied forces.
Prime: Awaiting counter-attack signal.
Prime: Once the war is over, we will help rebuild yours.
Prime: Today the Geth fight to secure our future.
Prime: We will not relinquish sentience. There will be no more compromise with the Old Machines.
Prime: Preparations are complete. We stand ready.
Prime: The Geth are prepared to face the Reapers.
Prime: New targets acquired.
Prime: Assessing platform losses. Sixty-four units offline.
Prime: Hostile contact!
Prime: Targets acquired.
Prime: Additional platforms will arrive via orbital drop once clearance is achieved.
Prime: Shepard Commander?
Prime: Tracking!
Prime: Deploying prime units. Orbital drop commencing.
Prime: Old machine forces spotted. Targeting.
Prime: Insufficient unit strength requesting reinforcements.
Prime: Creator squadrons are encountering heavy fire. Mobilizing support.
Admiral Raan
Shepard: Thanks Raan, good luck.
Shepard: I appreciate your support admiral. Those live ships will bring a lot of firepower, just keep them protected.
Raan: The live ships are safe, Commander.
Raan: We will do whatever we must to win.
Raan: Commander Shepard, a pleasure to see you again.
primarch Victus
Shepard: I want to thank you for deploying your fleet. How did they manage?
Victus: About as good as I could have hoped. Which is to say there isn't much of a fleet left.
Victus: Taking the main reaper force head on?
Victus: They were decimated. Earth is now the largest Turian graveyard outside of Palavan.
Victus: This is our last stand Commander. There are no more reinforcements.
Shepard: I never got the chance to talk to you about your son
Victus: I know I'm just one of many who have lost their son to war.
Victus: Then our victory today is for those who won't see their children again.
Shepard: Well your son gave us a real chance at winning this one.
Shepard: Your son honored the Victus name. He was a true hero.
Victus: Thank you commander. Hearing that... means a great deal.
Victus: Yes he... rectified an unfortunate mistake made int he past. I'm sorry I couldn't be more open with you about it.
Shepard: I'm glad we got this chance to speak.
Shepard: How are things back on Palavan?
Victus: The Krogan put up a magnificent fight. Fearless to the last soldier. Please make that worth something today Commander.
Victus: They bought us time to evacuate civilians.
Victus: Our alliance didn't survive and neither did millions of Turians because of it. Our only hope now is the crucible.
Victus: Then the bomb, our bomb, exploded on Tuchanka as you may have heard.
Victus: Wreav kept his word but he couldn't get the other clans to fall in line. We never got the reinforcements we needed.
Victus: Wreave kept his word, until the bomb, our bomb, exploded on Tuchanka as you may have heard.
Victus: And our civilian casualties have been far worse because of it. The Krogan lack... leadership.
Victus: But we still had support from the other Krogan clans. The female you saved rallied them. They were fearless to the last soldier.
Victus: Wreav kept his word, surprisingly enough. And the female Krogan you saved rallied the other clans. They were fearless to the last soldier.
Shepard: I'm surprised you're not back on Palvan.
Victus: I wanted to return the favor in person.
Shepard: Garrus said you pulled your fleet away from Palavan for this.
Shepard (surprised): Primarch Victus. I didn't realize you were here.
Victus: Good luck Commander.
Victus: May the spirits be with you
Victus: Commander.
Victus: Likewise.
Victus: Yet even then the Reapers were still too much. The only hope for my world now is victory here on Earth.
Victus: Urdnot Wreav was true to his word.
Victus: Urdnot Wrex was true to his word.
Victus: Wrex pulled out, the lying bastard. We never saw him again.
Victus: This war will be won or lost today. Here. On Earth, not Palavan.
Victus: He made our choice rather clear.
Victus: Yes, Commander.
Victus: And history will record that the Turian hierarchy stood among the brave.
Victus: Everything comes down to this moment.
Victus: As promised, we didn't forget where you live.
Victus: Though I'm sorry to see your world look as bad as ours.
