naw, they have nothing to gain from a price war. if PS4 went to 350, the XB1 would be 299 within months. MS knows it cant compete with Sony at the same price point.
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
