Well, BD remasters of original TV series are coming next year.
So it's quite possible they might throw some more money into one of the side works, either the Raising Ikari project for a bit of light hearted things, or ANIMA for some action, though I have no idea how far along ANIMA is storywise, while Raising project recently ended.
There is also the question on how will 3.0+1.0 finish, because it might end up giving us a hook with more questions.
I mean, TV series was rather straightforward in almost everything in it, except for the somewhat vague ending, at least to me, since I don't know if people rematerialising from LCL at the end will live in a normal world with normal seas, or will they have LCL seas and pitched MP Evas everywhere or what.
As for the 3rd movie, it was a mixed bag. We were shown Gendo and Fuyutsuki mountain climbing in previews, they did none of that.
