Back in film days, there was an EOS 3 that sat between the 5 and the 1 series. Back in the early digital days, the big question on everyone's lips was "where's the EOS 3D?", and I was only thinking the other day that the time might be right for an R3. Think there's certainly room for a high speed body and a high res body above the R5, for instance.Is this a new tier. We have the RP, R, R5, R6 and presumably the R1 so what purpose/role does a R3 fit? Super high megapixel camera?
