I think they might make that 85mm an f1.2, just like they did with the 50mm. Would be interesting (and of course, expensive).
The 28mm small lens makes a lot of sense (classic street photography) and the 40mm kinda too.
The 200-600 is not in the S series?
Seems everyone but Sony abandoned the once popular 135mm
Sigma has a fairly new 135mm f/1.8 - albeit just for DSLRs.
I think 135mm is either too short or too long for mainstream purposes.

Nikon has a fairly new 135mm f1.8 too, btw. A bit newer than that Sigma. And the 135mm from Zeiss and Samyang are not that old either. It remains an important segment, albeit it takes a back seat behind the 50mm and 85mm lenses.
