I also do not believe that we will see an upgrade to this lens any time soon. Although, if they did, I'd love to see an extra 15-20mm on the long end, updated IS and L build quality. But, then again, if any of those improvements were to be proffered, we'd likely have to pick only two. This EF-S lens must remain subordinate to it's EF counterpart, IMO. An EF-S 17-70 IS "L" II would, on paper, be superior to the 24-70mkII that Canon just released. But, it would be nice if Canon would release a general purpose zoom that matched the 7D's build quality and class leading architecture. One can dream......
