Forget the WiFi for those of us who use the best alternative - LAN cable shielded! No new Wi-Fi is ever going to beat that!
All that said, apart from the increase in hard disk capacity, i'm not very impressed. But the Move bundle is very interesting. Considering what Microcrap just dumped with its new black slim thingy - don't think i'm not excited. i am. but knowing what MS did last time it launched a console (i own an xbox and xbox 360) i will definitely wait before buying this new thing, as it's bound to have something loose or whatever that will need a newer version.
PS3 is rock solid, but i still think Sony needs to step up its game (roughly 7 hours to go before they drop down on the E3 floor and i've got to find a place to sleep by tomorrow) by launching a PS3 slim that heats up less, to begin with. My own PS3 slim and my friends', they all heat up way more than the last generation of Fat PS3. Good thing i have one of those as well to compare everything i switch them on.
The real verdicts will fall after E3, when everyone has had enough time to dissect the new hardware and test it out properly.
