While I really wouldn't take VGChartz' sales as gospel (nor would I include Zelda on this list), they still give you a decent idea of how much these games sell. To replace the 3 Zeldas, I'll submit 4 high-profile Japanese titles. I'll assume that you were only looking at the US sales, which is why Tactics PSP wasn't on the list.

According to VGChartz, 1st week sales in Japan:
-FFTactics Advance 2 (DS): 153,388
-FFCrystal Chronicles (DS): 196,120
-FFTactics War of the Lions (PSP): 165,901
-Monster Hunter Freedon 2nd G (PSP): 857,429

As far as upcoming US sales of games go, I don't know. I don't know exactly how popular Fallout is. I expect Pokemon to be inexplainably popular and Tactics Advance 2 to do pretty good, I don't think White Knight story will be particularly successful in its first week, and Fallout is kind of a wildcard. Though spread out across 3 platforms it could do better.
