Sony has announced that PlayStation Vita has sold half a million units since launching in Japan on December 17.
Vita went on to release in Hong Kong and Taiwan on December 23. It launched with 24 games, and Sony says more than 70 more are now in development for the Japanese market.
PS3 sales exceeded 3.9 million units worldwide during the holiday sales season, which ran from late November to early January in Sony's book, and remains on track to reach its annual sales target of 15 million units in the fiscal year ending March 31.
PSP sales topped 1.6 million units during the same period. In total, 6.5 million PlayStation systems were sold during festive period, according to Sony estimates, which suggests the ageing PS2 chipped in with 500,000 sales.
Sony Computer Entertainment head Andrew House suggested ahead of the Vita release that a successful launch could help give employees a morale lift following a "pretty tough year" for the company as a whole.
"From the SCE perspective, I think a lot rests on the success of PS Vita," he said. "We went through a very tough time in the company in getting to a point of [PlayStation] profitability, and I think we're now beginning to enjoy the benefits of that - it gives us some more leeway in being able to look at the future and areas of new investment in terms of new business models and new approaches to gaming."
