DSLR magazine has a whole article on the upcoming Nikon mirrorless camera. The two interesting bits of information are the expected release date (March 2011) and the statement that the “ The new Nikon mirrorless system would be more professional than what's offered by other companies “.

Here is a list of patents filed by Nikon that could be implemented in their mirrorless interchangeable lens camera:

• - lens that can be zoomed manually and electronically
• - interchangeable sensor
• - rotating mount
• - clever way of implementing bounce flash
• - backside illumination image sensor
• - a large EFV with a mirror
• - camera integrated email client
• - curved image sensor
