Personally, I expect games that try to push the graphical limits of any of the next generation consoles will mostly be rendered at 720p@30fps; while most games are modest improvements over current HD console or Wii games rendered at 1080p@60fps.
The reason for this is simple, I do not believe that anyone is willing to take on the expenses associated with a cutting-edge game console at this point in time. Consumers are unwilling to spend (much) more than $450 on a console, console manufacturers will be unwilling to lose billions of dollars up front to keep the cost of a high performance system reasonable, and publishers/developers are not going to want to increase development costs 2 to 4 times to produce games for these systems to (probably) only go broke after selling millions of copies of a game.
