People very optimistic here. 3.rd party lens makers that can get along with only one mount to work with both EF and R line on cameras will not go for two before the volume tips very clearly to the mirrorless side. They have almost no incentive and its very uncertain the glass will be or work better than what they already can achieve by just keeping up copying the EF software to their best ability
