Sony CEO: Worldwide PS Vita Sales Top 1.8 Million
"About Vita, the last year, [we sold] 1.8 million units in the U.S., Japan, Asia, and Europe. And as a starting phase, I think it was a good start," Hirai said via a translator, according to Eurogamer.net.

That amounts to about 600,000 PS Vita sales a month since it was introduced, and at that pace, it would impossible to sell 10 million units by this time next year. However, Hirai's banking on upcoming software titles turning the tide.
"A game platform, like Vita -- the software is the key to success, how good the software is. We have to reinforce the software area in order to improve the business, that is the basic line," Hirai said.
