Velvet, haven't you mentioned you have an X360? It's also being released on that.
My console history is extremely complicated, I tend to buy them and then sell them because I never use them. I got a Wii and sold it because I never turned it on for months. I actually got a PS3 for blu-ray at one one point and then realized I don't care about blu-ray and sold it.
It deserves mentioning that I sold both for more money than I paid for them, due to the Wii's rarity at the time and the PS3 being an early backwards compatible model.
All that said, I never bought a 360 ever, the exclusives when you have a gaming PC are extremely trivial. My girl does have a 360 though, and we live together, so I guess to be technical I do own one? Yeah, I suppose. I can't play FF13 on it though because it's the inferior version, and I am super psycho about that kind of thing.
