Sony's conference offered up reassurance that a number of their titles will be playable at this year's E3. The controller will sense movement, allowing the player to move an onscreen avatar 'naturally'. They also released the system's launch details. The North American PS3 launch will occur on Nov. 17th, 2006. The 20GB HDD version will retail for $499, and the 60GB HDD version will go for $599. They promise 4 million launch units by December 31st. Update: 05/09 03:57 GMT by Z : Apparently, not only does the $499 system have a smaller harddrive, but it has fewer features as well.
