It kinda irks me when people start talking about upgrade paths, you're not entitled to a new thing just because you bought the old thing. If they should worry about that then why release anything new at all, there will always be people who just bought the older thing, it doesn't mean you deserve to get the newer thing cheaper.
Also there is no way this will have anything to do with 4k, its still nowhere near powerful enough so don't get your hopes up. Games probably wont have more effects or be any prettier on one over the other, I'm guessing its about better frame rates because the current consoles are suffering for performance already and its still early in the cycle.
