The Canon Rumors website reports that the Canon EOS 6D Mark II will also boast a slightly taller and deeper body design than the current 6D, and will also feature built-in WiFi and Bluetooth capability.
Canon Rumors says the EOS 6D Mark II will be announced in July, with shipping beinning in August.
It also reports that a replacement for the EOS 100D / Rebel SL1 will be announced, the EOS Rebel SL2. Fewer details are known about this allegedly new entry-level DSLR.
Of course, these are all just rumours. Canon has also been said to be working on a full-frame mirrorless camera in recent weeks, so anything is possible.
