Canon M mount has NO future. I predict that Canon discontinues it, within two years, most likely unofficially, like Nikon did with their Nikon 1 line. No official announcements, but no new products, and let it fade out and die.
Canon EF will be around for a long, long time but Canon is gonna put all its effort into EOS-R, its full frame mirrorless format.
Don't buy EF-M stuff and waste your money, you've been warned.
Canon EF full frame lenses are a smart, stable buy because many of the Sony A7 guys buy them, because of the problems with the Sony lens line up.
