Sony says it will start a movie download service for its PlayStation 3 home console this summer in the U.S.

Kazuo Hirai, who heads Sony Corp.'s video game unit, said Thursday the service will be offered in Japan and Europe at later dates, although details won't be available until next month.

Hirai said the company will strengthen its network services and further cut costs to achieve profitability in the Sony gaming business in the current fiscal year ending March 2009.

"Please expect more from our evolving PlayStation business," Hirai told reporters at the company's Tokyo headquarters.
