I've been shooting Fujis exclusively for the last 6 years. IMO the f/2 versions of 35, 23 and 18 are superior than their 1.4 siblings. They're also much cheaper and lighter (not to mention weather resistant).
Would love a sweet deal on either the 50-140mm or the 16mm, as those are what I need to complete my kit. However, the 35/2 is alot more likely I think to get a drop, and WR would be very useful too...
The 55-200 is what I'm most after as its light and fits perfectly with my 18-55 lens lol, however I'd seriously consider the pros v cons of the 50-140 f2.8 too if it became available. I guess for holidays I'd be inclined to take the first with me, but portrait isolation I'd go with the 2nd, but I wouldn't take that much glass (and weight) on a backpacking trip.
