Cloud gaming is very much the future. Xbox being successful at Cloud gaming doesn't make "traditional" gaming dead, its just a different front of the genre. I'm always so fascinated by statement based headlines, why not just make it a question instead? I guess it's being bold. But, many a statements have been made "PC Gaming is dead" "This is the last generation of consoles."
I think we'll definitely see some form of Cloud gaming from Playstation this generation, Xbox is already there. Not everywhere they'd like yet, hi Apple

, but they're just getting started. Nintendo likely won't get to cloud gaming anytime soon, I give them at least 4-5 years. And there's Stadia, I think Google will make another big push for Stadia. If it doesn't catch on in the next 2 years it may likely disappear.
