Been tempted to get a Bloodbornestation 4 for a while which seems to have some good stuff in line and also seems to have it best as far as quantity. There's the third party stuff like Dark Souls 3, the next Deus Ex, Nier Automata, Ni-oh, Persona 5, indies, etc; keep in mind Ni-Oh and Nier are exclusive. There's some of sony's own stuff like Uncharted, Kojima's next project (looking forward to this one myself) and other things I don't really care to mention. I don't really care for the amount of hype it has, since I feel it is unwarranted and therefore a negative in my book.
I'd say the WiiU still has a pretty decent library as far as exclusives go, although I'm not as fond of some as many seem to be. Personally, I'd say The Wonderful 101 is still the killer app and a strong candidate for the best game it has. I haven't played most of the new ones like the Yoshi Wool game and Splatoon, athough those seem pretty solid and it seems a lot of people like Splatoon in particular so there's that. Only real problem with the WiiU as far as I can tell is the slow schedule, amiibos and the possibility that they might put it to sleep after Zelda U (which I'm sadly not very confident in) and I feel I'm being generous with that estimate.
I don't care much for Xbone since I'm kind of a weeaboo when it comes to games, but I'm jealous they're getting Scalebound. If Kamiya works his magic again, he'll probably make the best game on the Xbox One, just like he did with the WiiU. Probably won't be playing, but I'm hoping it turns out good.
