In an interview at Dpreview Sony said they are working on:
1) Telephoto FE lenses
2) Fast FE primes
3) f/2.8 zooms
So, let them now on out comment system what are the three FE lenses they should come up as next! I will sum up your suggestions in a POLL to be posted in 1-2 weeks.
I will be the first to start with my three suggestions:
50mm f/1.4
150mm f/2.8
24-70mm f/2.8
