Im not so impressed, I expected blu-ray to drasticly pull up PS3 sales beyond the 100k point, though this is barely a victory in my books, its still on the margin of error, and the two consoles are basicly = in this weeks sales. Though I keep wondering what would happen if the PS3 was priced the same as the wii in this region.
