Nikon mirrorless camera to arrive in April, P500 in February?

Nikon rumors are busy making rounds on the Internet and apparently Nikon is planning to unveil its mirrorless camera sometime in the near future. A rumor pins the mirrorless camera to launch in April and it might use a tuned Sony sensor, possibly a 16- or 24-megapixel variant, though the former is most likely. Another rumor involves a prosumer camera, possibly dubbed the Coolpix P500 and is slated to replace the P100. Improvements will include a 36X optical zoom and the inclusion of a lens dial to adjust the zoom. A 12-megapixel back-illuminated CMOS sensor was mentioned, and should perform well in low-light scenarios. If the rumor turns out to be accurate, the camera might be arriving in February.
