My brother will be glad to hear this. He played the game lots when he was a kid and is more of a classic sonic fan. He's also a bit of an xbox nerd. He was waiting for this to be released, he got the previous 2. I might buy it aswell, since I have so many marketplace points. I think it'll be the 4th copy of the game that I'll own =P

I'm more a classic sonic fan also, but I also think the new games are good too. Anyway, I'm glad to hear the news.
