This is why I think so:

Inafune and Comcept are still working on Mighty N.9 (how can you delay so many times and indie game?) and Red Ash, while Armature Studio is working on Dead Star. I can't see this game coming out anytime soon with all this projects in the way, especially if ReCore is a big budget title.

Also, when a publisher (especially Microsoft) presents at E3 a game with a CGI trailer, it usually means that you have to wait two years at least and we have several examples, Scalebound, Halo 5, Quantum Break, and so on. 

Considering that we still didn't see any kind of gameplay I really doubt the game will come out this year, unless we are talking about a mid tier, low budget title.

What do you think about it? Agree, disagree?

Disagree since Might No.9 is almost near going gold and Dead Star looks like a simple sci-fi shmup so they can't exactly be too busy ...

Plus I think ReCore is some low budget title ...

Yes, I can see it coming out in 2016 if it's a low budget title.
