This info comes from a source whom shared a couple of correct rumors in the past but also was wrong one the A7sIII rumor he shared in September. So this means we have to take it with a grain of salt. But I certainly hope he is right on track with reliable rumors when it comes to the info he just shared:

Part of roadmap for this year contains lenses:

400/2.8 FE (confirmed)

16-55/2.8 E

135 f? FE Part of roadmap for this year contains cameras:

a5x00

a7s3

a73 Next Samyang lens should also be 135mm probably f/2.8.

Thanks to the source for this!
