I can't find the roadmap diagram anymore, so no. 210? Why?
Nothing terribly significant but the FL range oval on the roadmap goes
deliberately past 200mm (the DA 50-200 stops obviously at 200).

I just reckon that an f/4 version would be hard to market as being
better than the DA unless it was well touted as being super sharp wide
open (hard to imagine). I suppose there's always the FF thing.
How well did the FA*80-200 sell? Sorry, we would all love to have one...
Pentax is a different company, with a different following.
True. Time will tell, but I don't think they'd be wanting to replicate
the DA lens so much. It could always be the beginning of the supposed
"replacement of all the (discontinued) FA lenses with D-FA lenses" that
you hear so much about if you listen to the rumours.
Cheers,
