The PS3 is a great system but this commercial just makes them look tawdry. If they feel the need to attack their competitors then they're just as pathetic as GM and Chevrolet have been this past year attacking Honda in EVERY commercial. I like their other ads but this one simply failed.
In that respect, yes, it's a little lame. But still.. i found it funny. The thing is, they're not even lieing - you really do have to do that with Wii and Natal, which is why i liked it.
I really dont like the idea of Natal for most games, boxing it might be good if the tracking is accurate and fast, but driving and fps games.. forget it.
What i'm hoping sony does is to make absolutely sure the games use the Move controller really well, with true 1:1 tracking and no precanned movement to activate game animations (like the wii). The tech is strong enough, i've watched all the tech demo's wrote by the R&D guys making the Move controller, it is certainly precise enough and the PS3 is powerful enough to offer true 1:1 tracking in the tech demo's, but implementing this into games by dev's which don't really know how the Move controller works is another matter.
I'll probably end up getting Natal and Move though, just like i got the WiiMotionPlus.
