Also, I laugh at all the people calling stupid on the DS3. Sony is not launching a completley new controller scheme. They are launching a product that runs along with the DS3. This is a fantastic idea. The DS3 is incredibly light, far lighter than the 360 controller(which is probably what most of you calling crap are holding to compare). It also has the absolute best feel for one hand, it has the best stick and the best pad feel. The only thing it lacked over the 360 to be the best controller ever is the placement of the second stick, which is now a wand. The wand is so unbelievably accurate. Watch it, it doesn't shake or drip/drop at all. The wii reticule is all over the place, even with motion+. Sony have really crafted a fine piece of hardware here, as usual. Expect a DS3 that cuts in half or a single analog stick for the controller. However, there is no reason for me to get that, because the ds3 and a wand will far out do every other controller scheme available this generation besides kb/mouse.
Seriously, go pick it up. Its very light, and it feels much better than the chuck.
The LBP Play was amazing, very nice to see.
