Being a huge sonic fan, i cant wait to play Sonic: The Dark Brotherhood, but i need to first get a DS. Now i dont want to get just sonic games if i get one, so what else should I look into?

So yesterday I found out the the new Spyro game that was origionaly only comming out for the PS3, is now being released for the 360 as well. This to me is a huge selling point for the 360 now, but I'm not sure which is a betetr choice...

I know this is of discusion, but I feel, that bringing Ace Combat 6 to the PS3 would be the best move for the series, seeing as it origionaly started, and ran compleatly with sony, (AC,AC2,AC3,AC4,AC5,AC0,ACX - for the PSP), it was nice to see a GBA game of ace combat, ACA, but i was truly disapointed when i saw that AC6's developers - Bandi Namco, in my opinion sold out by realeasing AC6 only for the 360, and not for the PS# as well. I think this was a bad choice overall, alot of sony people, who have hadall of there systems, like myself are now missing out on an awsome game, because they were looking for not how to please the gamers and there fan-base, but they were thinking only of what whould make them the most money, even though, had they realeased it for the PS3, there profits overall would have been much larger.
