Naaw man. I'm thinking Pokemon Company could be the other problem. They're in charge of marketing, merchandising and the Animes and you know the game gotta be out in time for that anime. I just dont think that Nintendo had any major hand in this because GameFreak has been on this path for awhile.
Eh Nintendo may not be encouraging them as far as we know, but they aren't stopping them either by having them delay the game like all their other developers are willing to do. Naturally they stand to gain more profits with Game Freak putting in the bare minimum resources.
