The head of Sony Corp.'s PlayStation division hopes to raise its profit outlook for this year, in stark contrast to the electronics firm's mobile business, which has forecast deep losses and sent Sony's stock reeling.

With Sony's three core electronics businesses — the third is imaging — looking increasingly lopsided, the company is having to shrink and restructure in mobile, and focus its growth hopes on image sensors and the 20-year-old PlayStation games console.

Buoyed by strong sales of the latest PlayStation 4 and the rollout of games and content for its network services, Sony Computer Entertainment CEO Andrew House hopes he can again raise the division's profit forecast for the year to end-March. Sony pushed up that forecast in July to ¥25 billion from ¥20 billion.
