Ι have thought about this a fair bit and I concluded that the best 35mm option for the x-pro1 is an x100 or x100s depending on budget. There is nothing else out there so wide that is particularly appealing or works well with this camera, unless you go to manual SLR lenses which would probably destroy the camera's form factor with adapters etc, but the main problem is that this isnt really the best camera for manual focusing (no focus aids and low res EVF)
On the other hand an x100/s gives you a spare body which is always a good idea and adds to the system some nice options you can revert to like the high flash sync, quiet shutter, flat package, without changing much in terms of workflow or UI. And by the time the 23/1.4 is launched the priced diff won't be much either.
On the other hand you lose one stop, and the x-pro2 (if/when it comes) will likely be a much better cam for manual focusing. So I dont know, it depends on your needs... I decided to skip the 23/1.4 sight unseen and went with the x100s option
