Dude, I have a 360, PS2, and Wii and I'm enjoying playing some "new" old games on my PS2! 9timesplitters hell yeah!)
Please don't buy a Wii, it's fun for maybe a couple months, but then....so sorry, I was busy shoveling third party Wii titles into the furnace. ANYWAYS, even I would buy that PS3 from you, seriously can't wait to get one.
Bottomline, you're going eventually spend $200 at gamestop, so get the $200 credit.
