The company has three forthcoming weather-resistant lenses on its 2014 roadmap -- the XF18-135mmF3.5-5.6 R OIS WR, XF16-55mmF2.8 R OIS WR and the XF50-140mmF2.8 R OIS WR -- and the 18-135mm lens is slated to ship in May. Keep in mind that the 18-55mm kit lens is not sealed, however.

If you're going to spend $1,700 on a kit, there's a long list of alternatives available, from full-frame dSLRs and ILCs like the Nikon D610, Canon EOS 6D and Sony Alpha ILCE-7 to fast APS-C models like the Nikon D7100 or the Micro Four Thirds Olympus OM-D E-M1. I think the X-T1 offers the nicest shooting experience without sacrifices, but still like optical viewfinders for fast action, and the E-M1 performs generally faster overall. It's a tough call, but the X-T1 does deserve a place on your short list.
