Yes, that is correct, Sev. The slim 360s have built-in wireless capabilities.

And for anyone interested in getting the new model, but have the old one, I believe there's a trade-in program in effect now at Gamestop. I don't know the details, but there may be information at their website.
...the 360 is an incredible machine that has chugged along for a good 5 years with no signs of slowing down.
From all the press conferences, I've gathered that I'll be picking up kinect for child of Eden, and a 3ds.
Right now, for me there isn't enough interesting software for Kinect that will get me to buy one as of right now. The tech is pretty neat, but there isn't enough games for the core player to enjoy right now. We'll just have to see what comes later.
And it seems the 360 is losing steam when it comes to exclusives that aren't for Kinect. This year, I've only seen Halo: Reach and Gears of War 3 being exclusive for the system. There's still multiplatform games, but exclusives really help keep people interested in playing on a particular console, and after their conference, I wouldn't be surprised if some Xbox 360 fans have jumped ship.
