Yeah basically. Think about all the best games on the 360 today or about to come out! Now think about it. Most of them have something in common. They are not using last gen engines. Lost Planet, Gears, Mass Effect, Dead Rising, PGR 3, etc.
Well since PGR3 was a 360 launch game then I guess that's the first next gen game
Anyways, conversely, who is winning the next gen ball? My guess would be Capcom. Way to go. I think this will make other prominent Japanese developers take more notice that they need to be really multiplatform devs in order to succeed in next gen and future gens.
Capcom initially expected Dead Rising to sell 660,000 copies by the end of 2006.
Now Capcom announced that Dead Rising sold 930,000 copies by the end of September.
