A Nikon 1 camera patent spotted by Nikonrumors.
After Fuji and likely Canon also Nikon will soon announce a new mirrorless cameras. Nikonrumors reports that Nikon will announce a new rugged 1 camera on Thursday morning (London time). No specs are known yet but it may be based on current Nikon 1 cameras.
I am still not sure about when exactly Canon will announce the new EOS-M cameras this week. Sony, Olympus and Panasonic will announce more stuff in October.
