It has been reported that Sony has filed for certification in South Korea for two new PS3 models: CECH-4205B and CECH-4205C.
A Kotaku tipster has said that the new models could be slight variations of the super slim PS3 (CECH-4000), and that changes could include: a smaller nanometer architecture, lower power consumption, and better cooling.
Apparently, a new PS3 model, CECH-4200, was spotted earlier this month on a webpage for Japan’s Minister of Internal Affairs and Communications. It could be that the variation in model numbers between the South Korean and Japanese filings could be regional.
