Honestly I am kind of surprised to be honest. GameFreak is a Nintendo studio and Nintendo isn't really known for rushing shit out the door to make a quick buck. MOST of what Nintendo puts out is quality. And even if they aren't top notch in the graphical department, you can at least count on Nintendo games to not be buggy, not have weird graphical issues, that sort of thing.
I mean how fucking long did people wait for Breath of the Wild. I don't think they are rushing to pump shit out. And since Nintendo has that level of quality for the most part, I'm surprised they are letting GameFreak get away with basically making their shit look bad. Especially since they just released a main-line remake set of games to bring in plenty of income of the fiscal year/quarter.
