These are the days of extreme ISO. The practicality and marketability of something so large and expensive would be next to none. People are much more likely to simply bump the ISO up one stop than to pay more and carry more for that extra stop.
...although I have to say that high iso\'s have opened up low-light photography. I take far more pictures without flash than I used to, because I can, just about. But often it\'s difficult, and I don\'t spend much on zooms as a result. An f2 standard zoom would be number 1 on my shopping list, even if it was quite big and didn\'t have IS. I don\'t own any f2.8 zooms now because I feel that f2.8 is one stop beneath the threshold that makes night-time hand-held shooting commercially viable. As a wedding and event photographer, an f2 standard zoom would absolutely rock BECAUSE of the availability of high isos. I could carry one camera instead of three.
As I 5DII owner I would have assumed f2.8 zooms would be fully usable for you at ISO 3200 or more. I often get away with f2 at ISO 1600 at events, so when I do the math it only makes sense that f2.8 would be perfectly usable at 3200.
