According to Carmack, “I don’t think there’s going to be much of a push for another generation for a long time. Really, we could be doing great, innovative work even on the current generation for many more years yet. It’s not like anybody’s seen everything that you could do.
“I’ll be surprised if we see radically better games enabled because of the new capabilities on the consoles, and, I’ve thought for a while we’re now past the knee of the curve of the payoff benefit, so we’re going to be definitely on the gradual sloping part of it going forward.
“Whether we get something like cloud gaming owning large shares of the market before (next-next-gen), or people using both systems or you just play on your mobile phone and it shows up on whatever screen’s near you, that could become (the) dominant gaming platform.
“But, a traditional next Xbox? Yeah, I think that’s a long ways off, and there’s a credible argument to be made that there may not be another console generation as we know it now.”
