It'll be like 2 years until a must-play game even comes out on these things. The PS4 versions of next-gen games aren't going to be playing differently like you had at the start of this gen with last-gen versions being hamstrung because the PS3 has 256 MEGABYTES of RAM. That Xbox video didn't show anything but improvements to old games and a tech demo of something that didn't show any kind of gameplay that can't be done on current systems. The switching games is cool and all but it doesn't make the actual games PLAY any better, plus how often are you even switching games.
