PS3 had only a couple problems: multiplatform games suck on it, and the cost on release was unacceptable..
Anyway, couldn't care less if there isn't a huge leap in graphics and the price is right. I don't play games because they're pretty. Even the best graphics fade from memory within the first hour, leaving gameplay, story, music, etc. to the heavy lifting.
However, I won't be happy if the console is focused on bringing new audiences in. I liked the Wii, it had a handful of excellent games, but I don't necessarily want another system like it.
