Good news for those who stuck with Olympus!

The Yahoo Japan report is based on a Jiji Press report of July 2. Jiji Press is a major press organization with a status in Japan similar to that of Reuters or the Associated Press.

Here is an accurate (that is, a human, ungarbled, non-Google) translation:

"In reply to reporter’s question at a press conference in Tokyo on July 2 announcing a new life-sciences microscope, Olympus President Sasa Hiroyuki revealed that Olympus had adopted a Sony sensor for use in its new mirror-less digital camera, the OM-D E-M5."
