So I just got my PS3, and now I'm getting the new 250gb Xbox 360 with built-in wifi! I ordered it off gamestop.com with overnight shipping, so I should get it by Thursday. Now I'll have all 3 current-gen systems. I also went to my local gamestop today to get everything I need and want for it by the time it arrives. I got a 1-year subscription to Xbox Live Gold, a 1600 Xbox point card, an HDMI cable, and a bunch of games (check what I just added to my collection for Xbox 360 on my gamespot profile).
I also reserved the new Mortal Kombat game for the PS3, and The Legend of Zelda: Skyward Sword for the Wii.
