Ancient Corp's Yuzo Koshiro(of Streets of Rage and Etrian Odyssey fame) had some pretty harsh words about the Switch in a recent interview with Polygon:
It's a really interesting interview though, you should read the whole thing. It goes into the history of Ancient and talks about their future(Which is where Switch came in).
"If Nintendo is going to keep up with the Switch, I think they'll need cheaper models, or maybe to make them lighter. If they were to do that, it could become a replacement for the 3DS ... but, of course, Nintendo has said themselves that that is not what they're planning to do. It kind of makes me think, 'Why does this thing even exist, really?' In other words, it's a game system that will allow people to enjoy Nintendo games even more, but at the same time, I'm not really surprised by it and don't really feel there's anything novel about it."
