Capcom producer Keiji Inafune, who's making the new zombie action game Dead Rising, said the console offers plenty of potential, but how much of that gamers get to see depends on how developers use its multicore architecture. "I believe that we'll be seeing two kinds of games for a while after the Xbox 360's launch," Inafune said. "Games that feel like something on current-generation consoles and games that feel like they're Xbox 360 titles."

"We had no intention to make Rumble Roses XX just a usual port. We were hyped, saying to ourselves that we're going to make it a completely new game," says Konami producer Akari Uchida. "But when it came time for the actual development, we realized that the volume of data [for the Xbox 360] would be one digit different [from current consoles]. The number of polygons per character by itself is 10 times larger than current consoles. ... It's as though we need to bring the quality graphics from prerendered movies into the actual game."
if these two quotes from japanese developers dont give you guys a better idea to how the 360 will shape up then nothing will.
