Microsoft's big announcement for E3 was to fully unveil Project Natal by its new name Kinect and now they may have quietly priced the add-on.

E3 is over for another year and Microsoft's big announcement was officially naming Project Natal to Kinect. What we didn't hear is what the add-on was going to cost us. Many sites like Amazon have priced the motion sensor for pre-order at $149.99 but no official price has been announced. Now we can add one more outlet to the rumor mill, Microsoft.com. That's right, Microsoft's own store has the add-on costing $149.99. Despite the item being up for quite awhile, Microsoft has yet to confirm the price but if it wasn't, wouldn't they take it down at this point? I gotta say they might be pricing themselves out of the motion sensor war at that price point. On top of that they will be pricing their games at $59.99 a piece which seems a little steep. We will just have to see how this all plays out when Sony and Microsoft go head to head again this holiday season.
