Due to the extreme high costs of developing this gen, I can see where you are coming from. But being exclusive can help the game, take Dragon Quest IX for example. Let's say this game came out on the PSP as well, it probably wouldn't have sold that much better in Japan and probably worse in the West as Nintendo would be less likely to put their full marketing muscle behind the game. That's not even taking into account the costs of porting the game, in short it's better DS exclusive.
