Could the PSP's big Holiday games outsell the DS's?

[09tarheel]

Updated the original post with the most recent sales data. The DS overtook the PSP for the first time, with the release of Pokemon Mystery Dungeon and Mario and Sonic Winter Olympics. Still the worldwide lead is less than 100,000 and the PSP has Grand Theft Auto this week. Will that be enough for PSP to overtake the DS again next week, or at least close the gap a little?

Also, if anyone is interested in this thread please post. When I update the thread for the consoles, it gets several new posts each week, but this one has not gotten any new comments since I've posted the numbers. So if you are interested in this please post so I will continue to update the chart.
