I'm interested, as I don't have a PS4 yet.
On the other hand, it really doesn't matter all that much, as new games will have to play on the old PS4 and, presumably, the old Xbox One. Game-play and design limitations will be determined by the lowest common denominator. If Neo appearing means the base model PS4 goes down in price, I might buy that instead.
Me too, if that makes the PS4 get a good price cut that would be awesome.
