Thats the old controller the one without the SPEAKER IN THE CONTROLLER! Seriously the speaker in the controller is the most incredible idea. having your controller make the sound of firing a gun beats the crap out of surround sound. Cheaper too!
Concerning the controller, I think it's the best thing of all time. I think i was gunna say something else but I forgot now. Oh yeah, What with rumble, full motion sensing, a speaker and all being wireless, I wonder about the battery life. i really hope it's rechargeable in some way.
Also the conference was probably the coolest thing I ever saw this year. There was a naked girl dancing behind my comptuer screen but she wasn't as cool as the conference.
