A few thoughts:
1. The super telephoto primes are probably an indication an R1 is on the way.
2. I'm surprised there are no 14mm & 20mm f/2.8 (or faster) primes on the list, as wide primes is where the shorter flange distance is supposed to help the RF mount.
The RF flange distance is 20mm, so shouldn't a small quality RF 20mm f/2.8 be about as easy to make as the EF 40mm f/2.8?
3. The 135mm f/1.4 surprises me. Its going to be big & expensive, not give Canon any bragging rights, and my impression is it wouldn't be easier to make on RF than on EF.
I would expect the 85mm f/1.2 to be followed by an improved 135mm f/2, say with IS and faster focus. Or, to follow the first point, an RF 300mm f/2.8L IS USM.
4. Somehow, I'm still wondering why 50mm f/1.4 IS USM isn't on the list. The f/1.2 is expensive, and I expect STM to be slow.
