Recently appointed Sony overlord Kaz Hirai has pointed out that the PlayStation Vita is performing near expectations globally, but that it's "trending behind in certain territories". Earlier this month, the platform holder revealed that the system had sold 2.2 million units worldwide.

While Hirai wouldn’t reveal which territories he was referring to, it’s safe to assume that Japan is the biggest offender. Given the success of the PSP in the region, Sony must have expected more from its latest handheld. However, the nation is currently gripped by 3DS fever.
