Yesterday, Fujifilm gave the roadmap for the X-mount lenses in 2012 and 2013.
For fall 2012, a 14mm f/2.8 wide angle (equivalent to 21mm) and a “standard” 18-55mm (equivalent to 27-84mm) zoom with stabilisation and wide f/2.8-4 aperture.
For 2013, more primes and zoom: the anticipated 23mm f/1.4 (equivalent to 35mm), a 27mm f/2.8 pancake (41mm equivalent) and a 56mm f/1.4 (84mm equivalent), as well as a very wide angle 10-24mm f/4 zoom lens (15-36mm equivalent) and a 55-200mm f/3.5-4.8 (83-300mm equivalent).
No detail on pricing or exact availability, but this looks to be a promising commitment from Fujifilm on the X-Pro1 system. Here is the roadmap as published by Fujifilm:
