I just realized that if they were planning to release XY-sequels later this year, there would be no reason not push marketing with Zygardes forms in the movie this summer.. instead it's about Hoopa, and tons of old legends.
They would have certainly put the focus on Zygarde this summer if they had a game to follow within 8 months of the movie, just like they did with Giratina/Shaymin-Platinum and Kyurem/Keldeo-BW2 movies.
(Heres a game release date timeline I made, with posters of each years movie below them:i.imgur.com/yznVikk.png
I'm not sure what GF is up to...other than taking their time with the XY-follow-up game.
So either there is no game coming this year, which would mean the next one is XY2, early2016-summer2016
Or there is another filler game coming first at end of 2015, pushing XY2 further towards end of 2016, unless the filler game was something really simple.
But there isn't any serious choices for filler games..
-Delta Emerald (highly unlikely, but it'd be an easy cashgrab and not take too much development focus, allowing XY2s release come out summer 2016)
-some kind of Kanto revisit? (though that would likely just turn out to be a re-remake with megas involved, the same way as ORAS was handled...)
Frankly I wouldn't mind either... but both can be done in very different ways.
I can imagine a terrible cashgrab Delta Emerald, with minimum effort put into it, mostly just the Battle Frontier (which would still be fucking great on it's own though) and small bits from Emerald.. although Delta Episode doesn't really fit into this picture.
I can also imagine a "meh"-FRLG remake that wouldn't offer much new besides a bunch of Megas.
But at the same time I can imagine quality versions of those games, with things expanded and explored and fleshed out properly... but that requries "unnecessary" effort on GFs side, and we've seen what that usually means <.<
