1) Sony
2) Nintendo
3) Microsoft
Sony will survive simply because they're sony. They have the brand loyalty and exclusives that will deliver even when gaming crashes. Just look at PS3's early days of being on the market. No one wanted one and yet they managed to snatch second place from Xbox 360.
Nintendo isn't that screwed because that have very recognized ip's that people will still want to play.
Microsoft is the most screwed simply because of their vision. We saw all the backslash from their X1 reveal and they had to directly change literally most of their vision. Chances are it will happen again sometime this Gen.
This is my opinion, whether you agree or disagree is up to debate.
