The 2023 FF camera body will have the same 22MP sensor as the 5D3, but it will be announced in 2019 as 'pre-order' for delivery in late-2022. The APS-C flagship will have the same 18MP sensor as the T2i/T3i/T4iT5i/T6i/T7i and T8i as well as that in the 7D, 7D2, 7D3 and 7D4.
Oh yeah... as well as a touch screen 'retina' display, it may have a touch sensitive mode dial, plus true to Canon Inc. pricing policy of late, camera bodies (w/o kit lenses) will start from $19,999 or $24,999 with standard L zoom.
Finally, Canon will be re-branded 'YongMeike' and their HQ will be located in Shenzhen, China!
