When will the PSP surpass the Game Boy Advance?

[killer7]

The sales of the PSP are sloing down quite rapidley! Considered to be "walkman of the 21 century" and the "Game Boy Killer" it never matched the Numbers of the original version! But it could surpass GBA when all is said and done! The gap is around 6 Million! What do you think?

 

PS: First Threat- Wohoo!!
