I don't think there will ever be a 1DX3. . Nor do I think there will be ever be a 5D5 or a 6D3.
In fact, I don't think there will ever be any professional or prosumer DSLRs from Canon ever again, except possibly a 7D3.
I think the only DSLRs that Canon will make, moving forward, are low-end Rebel models; and even those will probably only be made for another year or three. . I think that all of the prosumer and professional Canon cameras from this point forward will be mirrorless.
