But there's still LOTS of characters I'd consider getting if Marvel made a movie of them; Hercules, Namor, Moon Knight, Blade, F4(please come home)...
Amen to wanting FF to come home. I not only want to see the FF in a good movie, but want them in the MCU; with the expansion into space and 'other realms' phase 4 would be great for F4. Of course Namor would also be great in the MCU too, one of the oldest Marvel/Timely comics characters they have and if they bring back the FF introducing these characters together would be perfect.
Blade could be fun to bring back, I like the idea of bringing back Snipes and introducing his daughter as the new Blade to pass the torch too. It's an idea that that they floated for the comics which has stalled and hasn't come out (yet?).
Hercules is a fun character in the comics but I wonder how they could make a distinction between him and Thor. There is more opportunity for humor with Hercules though (we will see how the humor plays in Ragnarok with Thor, but Hercules could take it to another level). I don't see an MCU version anytime soon, but who knows what happens down the road. I'd also love to see She-Hulk in the MCU, but again when it comes to future characters and figures, besides the FF, I pretty much have what I want already.
So I can see an occasional new character inciting me to get a new figure (FF would be a no brainier), but overall with already having 2 Caps, Thor, Iron Man (3 versions with 1 more on pre-order), Hulk, Widow, Hawkeye, Vision, Witch, War Machine (2 versions, plan to sell my Mk2), Falcon, Luke Cage, Daredevil, Strange, Wolverine (I know, not MCU) Spiderman (Rami version but Homecoming is pre-ordered too), and plans to get Black Panther and maybe Ant Man and Wasp down the road, I feel like my collection of Marvel figures is almost done. I'm pretty close to having all I really want.
