Fujifilm X100 vs (new) X-E1 vs (wildcard) Olympus OM-D

With Ricoh GR, landscape hurts due to sensor size. For the camera I am interested in purchasing, I am looking for a 35mm (film) lens. Possibly a 50mm later.

Since the Fujfilm X series are roughly based on Leica M's, I would say that give it time for weather sealing to be included. The new M (2013) will be the first Leica to incorporate weather sealing. Olympus has really pushed its weather-proof likeup for a while now and has probably cross engineered some of that advancements into their professional lineup.
