Sony PSP continues to do well against the Nintendo DS

For the second week in a row, the Sony PSP is outselling the Nintendo DS in the Japanese market. The latest figures point to continued strength for both devices, but the nascent trend has to be a little worrisome to Nintendo.
Regardless of what some people claim, the two devices are very much in competition, and the numbers game is a crucial measuring stick, as the industry watches very closely. The DS still has an edge in overall sales.

Also of interest in the list is the Xbox outselling the original Gameboy Advance. The numbers for the big, black box are still dismal, though.
