Game Boy Micro introduced in Japan on September 13, perhaps.
Rumor has it that Engadget reports that Next Generation said that some people in Japan may have hinted that Nintendo could be introducing the Game Boy Micro in Japan on September 13th. Engadget adds that it would be the 20th anniversary of the release of Super Mario Bros. for the Famicom, and they might have heard somewhere that special Mario games could be released alongside the Game Boy Micro.
