PS4, 3DS and XB1 will all be at least reasonably, if not hugely, fine (although 3DS is probably going to be smaller than DS). Ninty and Sony must really do more for Wii U and PSV, then the whole generation will be fine too. PS4 and 3DS are the most likely winners, but I'm sure that if Sony, MS and Ninty will do their best there will be enough room also for the others, like in 7th gen. XB1, despite its high price and initially horrible marketing and PR, is on the right road, PSV and Wii U need more focus and commitment and a lot better marketing from their makers.
