How much was it up in Q4?
About 9.5%. But all of that was from December. October and November were both down, with a net -27% from '04. But December '05 was up 49% YoY. December '04 was pretty damn rough for the PS2 in the U.S., down by nearly half from Dec. '03, so Dec. '05 seeing YoY improvement isn't surprising.
