Canon should bring 2 Models:
• EOS 3 - as small as possible, = like EOS M2, with 70D sensor, fast enough DPAF, some minor improvements, price exactly like SL/100D
• EOS M Pro = "Fuji XT1 killer", 7D 2 sensor, AF speed best in class, EVF, built in flash, built in wifi, GPS and RT commander, fully articulated "retina" LCD, beefier grip to fit LO-E6N battery for 500 shots per charge.
And never mind should those 2 models confuse some consumers. They can still go and buy a rebel or other mirrorslappers.
I am sure Canon will keep the EF-M mount. It' specs are well chosen and the existing lens line-up are all price-weight-size-performance leaders. Add a few more good, small and cheap pancake primes (e.g. 12mm/4.0, 50/1.8, 80mm/2. and a 60/2.8 macro and everythinv will be just wonderful.
I agree ..... I assume the M3 Pro will be named M3X ...... don't know why they both couldn't share the 7DII sensor - Canon need to use the latest sensors they have to avoid trailing the competition by too much. By putting a grip on the camera would allow a larger battery, one of the shortcomings of the current model
