All joking aside, what Canon has done is really impressive.
#1 in ILCs. Sure, down a bit, but still dominating. Also, it wasn't too long ago that the gap between Nikon/Canon was much smaller. So, this is really Nikon re-establishing themselves and a year Canon did not release any DSLRs of significance (just entry level DSLRs, M50 and EOS-R). Seriously, wow.
#1 in Mirrorless. After all the negativity, Canon is #1 in mirrorless sales. Again, wow.
#1 in lenses. A bit expected. Sell the most ILCs, sell the most lenses.
#2 in Digital Cameras. A very close second to Nikon with Sony a distant 3rd.
That is domination. Release a few new G series cameras, and maybe they are #1 in all categories for 2019.
I personally do not benefit from Canon's domination in the short term. But, as someone invested in a system, I have every reason to think Canon will be around for many years to come.
