You think the 360 is made up mostly of RPGs?
I don't think this generation is much 'FPS' anymore, just that FPS games are rising to popularity due to its online modes. This year is getting a TON of racing games, probably more so than FPS games.
Blur, GT5, Need for Speed, Split/Second, Mod Nation Racers, SEGA All-Stars Racing and a few others I missed. I think people aren't seeing the big picture and just take 2 or 3 games out of a period of 3 years and say "This is what is bad for gaming."
