You seem to ignore the post that mention the innovation and focus on the posts that bring up more minor things but not the examples. Personally and although many people didn't like the game Folklore to me was pretty innovative with how the sixaxis was used to rip the ids out of the wow it's been so long I forgot what they were called but anyway, what you feel is just rehashed with better graphics other notice what is innovative. I think what you are really wanting to say is why aren't they using the ideas that you would find innovative.
Some find any use of the six axis gimmicky and in some instances it is while in others it's very innovative.
Now the next question is are you only comparing to last gen or the other consoles as well if just last gen nosy has made major improvements with online, hard drive, plus other things.
Some things to you may seem only graphics but there is also the fact that the ps3 is capable of calculating some amazing physics which is why there can often be fun weapons that bounce all over the place. Or the often mention on this thread LBP
