As far as resale value on lenses, I can tell you from personal experience that if you hold on to a lens for a few years, you can get almost all of your money back. In 2005, I purchased a EF 24-70mm f/2.8L, a EF 70-200mm f/4L, a EF 50mm f/1.4, and a EF 100mm f/2.8 Macro, all new from Amazon. In 2010, I sold all four lenses on Craigslist for the exact same price I paid for them. They were all in very good shape, though the two L's had both been fixed by Canon after an unfortunate five foot fall onto pavement for both of them. The bottom line is lenses don't really wear and Canon keeps increasing the cost of new lenses. I purchased a 50mm 1.2L last fall and fully expect to be able to sell it in a few years for the original purchase price. Bottom line, the EF-S 15-85 seems like an excellent lens (haven't used it), will likely not have an update in the next five years, and you'll probably be able to make back almost all your money when you choose to sell.
