For the first time since its launch, Microsoft's Xbox 360 has outsold both the Wii and PS3 in Japan, according to Enterbrain. Hot on the heels of Namco Bandai's Tales of Vesperia launch, which already made X360 sales surge, comes Square Enix's Infinity Undiscovery, and combined with the recent price cut, resulted in the Xbox 360 selling 28,681 units last week, compared to Wii's 27,057 and PS3's 8,050.
