They talked about maybe some fixed length tele. Traditionally that would be 135f2.8, 180f2.8 and 200f4 come to mind as possibilities.

Considering the fact that they love to release direct APS-C equivalents of classical focal lengths like that it would translate into 90mm, 120mm and 135mm. I would love to have them at f/2 but would totally understand if they would choose to go more compact f/2.8 route.
Faster heavier tele prime will definitely be better balanced on a heavier and larger X-Pro1 body. X-E1 on the other hand is perfect with small primes like 27mm and 18mm. IMO both of the bodies have their strong and weak sides and getting a proper diopter for X-Pro1 will be much easier than selling it and getting another X-E1.
