I really do not expect from Canon something super new or super mega new technology

Take a look back to history: I remember all big expectations related to 6D. There were many wishlists but in reality Canon produced significantly crippled FF camera, which AF does not even match old 7D
Now I really expect that after 5 years Canon will launch 7DII, which will have 70D sensor, slightly more megapixels (expect 24 MP), slightly higher FPS, GPS and WiFi. That's it

Do not expect significant revolutions in sensor. If there were such revolutions, there would be a leak of information already. For example, Sony announced curved sensor technology, which will be implemented in their future models.
Canon made revolution few years ago. Currently it is a stagnant company, which still focuses significant aattention to dying P&S market. Product cycle for semi-pro and pro products is very long and shows that Canon does not sufficiently invest in R&D as other companies. Canon started loosing in the following areas:
1) Mirrorless market - they loose to Fuji, Olympus, Sony;
2) Sensor technology - loosing to Sony;
3) Lenses - starting to loose to Sigma and Tamron as these 2 companies started producing high quality lenses, which match or in some cases exceed qulity of Canon lenses (e.g. Sigma 50 mm 1.4 Art, Tamron 24-70 2.8 VC) for affordable price.
From financial perspective Canon is doing quite OK, even better than other companies, as they still have big loyal customer base, however, in technology companies if you loose momentum you can loos all business very soon.
