Actually, 28mm on APS-C isn't wide angle at all. Personally, I like the 28-300mm as a one-lens solution for travel, but on a FF camera only.

I'd really recommend considering a 2-lens solution, either the EF-S 15-85mm f/3.5-5.6 IS or the EF-S 17-55mm f/2.8 IS combined with the EF 70-300mm f/4-5.6L IS.

I don't expect an update to the 28-300L any time soon, the 100-400 will likely be updated sooner, (but that's been rumored for years, there have been 2 patents, and still no lens).
