How many lenses/ Which lenses do you plan on buying?

I bought the x pro for my travel camera. my last few holidays I have carried around a dslr and three or four lenses and it gets to be a bit much. I hope to take an extended holiday in a couple of years (6 months to a year) and plan to take the 18-55 and the 55-200 witch should cover just about all the bases and still be light and manageable.
