But why bother? This late in the game people buy a 360 because it's cheap and has a ton of games. They don't care about a turbo version slightly better than the old versio but not nearly as good as the machine coming out next year.
They dont care but they'll be forced to buy it regardless if they want to play 360 games.
Then you'll have people like me wholl rebuy it for the res and framerate increase.
If Durango isnt going to happen turn the switch and have the turbo be the next gen.
Like I said before the only risk is the R&D cost.
