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

[09tarheel]

I'm surprised by the number of people who don't even think it's a possibility. Here is a look at the games on the DS, and the sales of previous games on the DS.

-Pokemon Explorers of time has sold 4.45 million, but that included 1.5 million in Japan where Explorers of Sky has already released. Suggesting maybe 3 million total in the West, maybe less if follows the decrease in sales seen in Japan.
I'm guessing 1-1.5 million for this game this holiday.
-Mario and Sonic at the Summer Games has sold 4.33 million on DS. However the sales were not very front loaded and the summer games are more popular than the winter games.
I'm guessing 1-1.5 million this holiday.
-Cooking Mama 2 has sold 2.66 million. But this game sold based on legs not initial sales, it has also sold significantly less than the first Cooking Mama.
I'm guessing 400-600k this holiday.
- Call of Duty 4 has sold .58m in America and we don't have Other's data for the game. In America again this game's sales were based on legs more than initial sales.
I'm guessing 400-600k this holiday.
- The Legend of Zelda:Phantom Hourglass has sold 4.52m. However the game was bundled in America for awhile.
I'm guessing 1.25-1.75m this holiday.

That adds up to 4.05 m on the low end and 5.95 million on the high end. I think the PSP's potentially biggest games GT & GTA releasing at the beginning of October, giving them 3 full months of sales, at least puts the low end in reach.
