I don't think any company is ever really in a position to share what they're going to put out, with licensed product, you could want to do a lot, only get approved for some, or ultimately decide it not worth your effort to release something.
With this T2 license, they may have a plan right now for what they want to do, but until they do prototypes, get ideas approved or not by the license holder, or weigh in sales of items to see if it's worth their effort to release a figure, it's not wise to release a list.
I'd imagine, with Salvation, HT probably had Kyle Reese lined up early on as a potential figure, waited on fan reaction to make their choices and probably scrapped him as a bad business choice. Providing information up front pretty much means a committment, it's not in their best interest to committ that far ahead, then they'd be stuck making poor selling figures because they said they would and for a few folks it'd piss them off not to follow through. Releasing information as they're ready to sell it is the only way to protect their business interests. It's not just HT, Sideshow probably develops much more as they go, and certain factors dictate what actually comes out and when and you can't just up front say we're going to do this, this and this.
What they can do, and should do, is just release things in a way that's reasonable to the collector. Like with this T2 license, if you're ever going to DX a figure, do it first, make the original figure DX and be done, don't do 1 or 2 standard figures and then take them further and combine them into 1 DX set.
HT's walking on eggshells right now, with DX Batman, Joker and BD Iron Man, they've shown they'll tap into the fanbase's desire for the best releasing improved versions of figures people bought up the first time around, but, as we're seeing from the spread paranoia at this site, at some point, if they don't break out of doing that a lot, people will eventually stop buying first versions, I don't know how many rehashes it'll take to reach that point, but there will be a breaking point. Then again, maybe their local market has a totally different perspective on all this and there's no need for them to care about it. While there are a number of consumers outside of their local market, a lot is geared towards that and from what I read, the collecting culture is more respected over there and probably has a much different perspective from us.
