Ok I'll think about getting one, but should I sell my 360 to get it?
Um keep both
PS3 has the blueray built in
Bluetooth to boot
Same games for the most part.
- I wish PS3 had Forza, BUT GT5 will destroy Forza so I am not worried.
Better potential for graphics
There isn't much an Xbox can do that a PS3 cant

It is a solid investment just because you have a blueray player which sell on the market for $400+ might as well just get the console
