I keep seeing announcements for games that will be available for PS4/XB1 that will also be available for PS3/360. Very few games are next generation only. There just isn't enough of a boost in power for next generation consoles to make the games different enough. Don't get me wrong, PS4 and XB1 are a step up, but not like the differences between NES/SNES and PS1/PS2. They should have waited another year or two. They should have boosted the power of the systems a little more. There should be no trouble producing 60 FPS/1080p resolution at all.
PS3 would have ended up beating Wii--as it deserves--and people would not feel the need to buy more expensive consoles. Hey guys, I do like Nintendo, but the Wii is the worst system and idea that they ever produced, even if it did sell very well. It was not truly for core gamers and the motion fad was terrible. Wii U is actually a better system than Wii, but the casuals have moved on and it doesn't sell nearly as well. Miyamoto has finally revealed that they will focus on core gamers again. Smart choice Nintendo.
Anyway, PS3/360 gamers will not miss out on much over the next year or two, unless a moderate upgrade in graphics are really important to them.
