The next full-frame RF mount camera will be a replacement for the Canon EOS R | Canon Rumors

I think it unlikely that they’ll introduce a higher-spec (30ish MP) camera below the R6. More likely they’ll re-use the R6 sensor, and reduce the spec in certain areas to keep the cost down. Examples could include lower res EVF, fixed screen, elimination of IBIS, elimination of mode dial and buttons (by using advanced “intelligent-auto” metering, and dispensing with P, S, A, M). I’m assuming that the camera would be aimed at budget-conscious novices, who would probably prefer a simplified camera.
