I think this game is a "hold" now because the December numbers did significantly better than November. The game sold 171,000 copies in Dec compared to 42,500 copies in Nov. That's a pretty big growth rate. I don't know if this game will continue to sell as the future of the PSP is pretty mirky. This game may have just been a popular stocking stuffer. SOCOM Fire Team Bravo 2 is at a total of 213,500 copies sold now.
