Amazon and the Microsoft store both have Kinect at 149.99 so it's seeming likely now.
This really puzzles me since you can buy an entire 360 console for that price. Not to mention, if they are really trying to go after the Wii then this one device costs nearly as much as an entire Wii console. They still have time to change their minds, and this info could always be false.
Being the sucker I am, I will buy one...but I'll be waiting for the Kinect/360 Slim bundle that's surely coming this fall.
