I got this June 18th. It was $300 USD and so far is worth it. If you buy it from Gamestop with trades, you can get the price down. I bought mines from Best Buy though, for rewardzone points. LOL
Anyways, so far so good. No serious lag with the wifi. If anything MW2 seems to run much smoother than before. I can't want to play Black Ops on this system.
If anyone uses memory cards though, they don't work on the new system. No place for them.
I did notice that the machine runs pretty hot though but it's quiet like they say it is.
I'm going to sale my pro and elite and get one more of the new consoles.
