Firstly, get this out the way.
The DS has sold just over 40m WW, whereas the PSP has sold 21-22m. The DS has whipped the PSP ass with regards to sales.
Now where does the GBA come in.....?
Are there very strong sales of the GBA at the moment? I don't understand why your comparing the PSP with the GBA. The GBA has sold loads more units than even the DS over the course of its life and yes people still play them, especially really young kids. But I don't see why or how the GBA is competing with the PSP.
Anyway, as a footnote. Although the Handheld war between the PSP and the DS looks to have been won. This generation of handhelds is far from finished. There is easily another 3 or 4 years left in both the DS and the PSP, especially the PSP, so it's not over til the fat lady sings.
