PSP sales mysteriously double in Japan [Update]

We're happy for the PSP's newfound success in Japan. In fact, last week it sold 184,610 systems in Japan alone. That's more than double of last week's numbers! (That's actually more than any other system, minus the DS.)

But what could possibly have caused the sales increase? Could it have been Minna no Golf Portable 2? Only three games for the system made the top 50 charts this week, so it couldn't have been that. Perhaps it was firmware update 3.80 and its ability to record 1seg TV shows? It actually might just be that ...

[Update: Or it could be that new red PSP bundle. Whoops!]
