So much for their earlier denial, eh? An anonymous Sony official has "confirmed" to Japan's Nikkei that they will sell their advanced computer chip operations to Toshiba in an effort to re-focus on core business. The official announcement is expected later today. The sale gives Toshiba the manufacturing responsibility for the much hyped Cell processor used in Sony's PS3. Sony, of course, will continue to invest in the Cell chip. Nikkei says the deal is worth some ¥100 billion (about $858 million) and should be completed by March.
