Japanese patent application (2010-250149) contains some drawings of the upcoming Nikon mirrorless interchangeable lens camera. The news here is the flash (#14) which was not present in previous drawings (see here, here and here):
Nikon also filed a patent application 20100277599 in the US for a wireless transmission of pictures to a TV set/external monitor:
"Until recently, image data shot or reproduced by a digital camera has been confirmed by a small LCD display attached by the digital camera. In order to confirm with a large screen, the digital camera can output either digital or analogue video signal to an ordinary domestic TV set. Recently, various wireless LAN methods have been proposed. Among them, UWB (Ultra Wideband) or IEEE802.11g for one of a short-range wireless communication method realizes a data transmission rate of 100 Mbps, so that the waiting time accompanying with a large amount of data transmission is drastically reduced. By connecting domestic instruments including these functions with a wireless LAN, it becomes possible to construct a new domestic network that has never been accomplished."
