Sony has lowered its annual sales forecast for PS Vita and PSP, revealing in its second quarter financial results that it now expects the handhelds to sell a combined total of ten million units by March 31, 2013.
Those predictions are down from 16 million units forecast in May, which was then reduced to 12 million units in August.
Sony stuck to its sales forecast for its PlayStation home consoles of 16 million.
For the second quarter ended September 30, Sony's game division reported a sales decrease of 15.8 per cent year-on-year to 148.2 billion yen ($1.85b).
"This decrease was primarily due to lower sales of hardware and software of the PlayStation 3 and PSP, partially offset by the contribution of the PlayStation Vita introduced in December 2011," the company said.
Operating income declined year-on-year, from 3 billion yen to 2.3 billion yen ($29m). Sony said the "decrease was due to the impact of the above-mentioned decrease in sales, as well as unfavorable foreign exchange rates, partially offset by a decrease in selling, general and administrative expenses".
The company sold a combined total of 3.5 million PS3 and PS2 units during the second quarter, compared to 4.9 million during the same period a year ago. Handheld sales were down slightly too, from 1.7 million units to 1.6 million.
On the software front, the company shifted 41.4 million PS3 and PS2 games, up from 40.2 million a year earlier, while handheld software sales grew from 8.2 million to 8.7 million.
Overall, the entertainment and electronics giant posted second quarter sales of 1.6 trillion yen ($20.5b), up 1.9 per cent over the same quarter last year, while it reduced its net loss from 27 billion yen to 15.5 billion yen ($19m).
