A recent report from the Chinese language Wealth Group is stating that KYEC will start landing PS3 chip orders within the next few days. Not surprisingly, KYEC declined to specifically comment on any specific chip orders, and merely confirmed that PSP orders have commenced.
From the Wealth Group report:
Sources at equipment makers stated that KYEC has already started testing engineering chipset samples for PS3. The IC testing house also undertakes testing of the graphics processing unit (GPU) for the PSP as well as the southbridge for the Xbox 360.
