Vita sales are "where we would expect it to be," says Sony CEO Kazuo Hirai

Vita sales are in line with Sony expectations, according to Kazuo Hirai; however, Sony's CEO admitted sales were a bit off in some regions.

Speaking with Reuters, Hirai declined to say where sales were lower than expected, and didn't say whether slower sales has anything to do with difficulties attracting third-party publisher support - something he has stated previously.

"Worldwide, the Vita is pretty much along where we would expect it to be, maybe trending behind in certain territories," Hirai said during the IFA consumer trade show in Berlin.

Hirai's comments echo those of SCEA president and CEO, Jack Tretton, who said earlier this month Vita sales were “acceptable.”

Sony's Q1 financial figures lumped Vita sales in with those of PSP, with the firm citing hardware sales of 1.4 million, down from the 1.8 million PSP managed alone the year before. Software for both handhelds came in at 5.8 million, down from the PSP’s 6.6 million in 2011.

Earlier this month, it was revealed Vita sales had hit 2.2 million worldwide as of June 30, which was up from 1.8 million in May.
