With the CP+ show in Yokohama, Japan beginning on February 28, 2019, it's obvious we're going to see some significant product announcements from Canon ahead of that date. CP+ is generally a show that Canon uses to show a lot of new gear.
WPPI also begins in Las Vegas on February 27, 2019. You can see the 2019 trade show schedule here.
The latest word on the street is that Canon will be announcing new gear on February 14, 2019. This date is quite likely for announcements.
We think the Canon EOS RP will be announced, along with at least 2 RF mount lenses. The PowerShot G7 X Mark III may also make an appearance for this show, but is so far proving to be a unicorn. There's been no mention of any new EOS M or EOS DSLRs being announced as of yet.
