Japanese hardware sales, 29 May - 4 June:
- DS Lite: 135,614 149,411 (52.42%)
- PSP: 24,595 2,632 (9.67%)
- PS2: 18,513 1,285 (6.49%)
- GBA SP: 4,364 2288 (34.40%)
- Game Boy Micro: 1,270 743 (36.91%)
I should note that we caution against putting too much weight on these sales estimates, especially in a comparative sense. The PS2 and the Xbox 360 are at opposite ends of their “console lifecycles,” and the two are priced quite far apart as well (e.g., $129 vs. $299, PS2, Xbox 360 Core respectively).
