Definitely not as much as had been hoped for, but given that Sony's price cut on the PS3 wasn't a real price cut, and this would be a permanent reduction in the price of the box if it comes to pass, it certainly puts some more pressure on Sony and offers Microsoft a chance to keep up the momentum at the high end of the console market place.
