It's not THAT revolutionary, Olympus have had a 14-35mm F/2 for their DSLRs for a good while and that's unbelievably good quality. I know a professional press photographer who shoots Olympus specifically for that lens.
But it's the equivalent of a 28-70 f/4. A pretty mundane lens, wouldn't you say? The Sigma is the equivalent of a FF f/2.8 lens. That's a full stop extra in light gathering power.
I don't think Canon would invest their money in pursuing a lens like this, unless Nikon came out with one. I feel Canon would rather make more Rebels with no upgraded features than invest in their devoted/professional crop body shooters. Canon like to deal in extremes, ignorant amateur or needy professional.
APS format cameras are still the top-selling cameras in C and N's lineups. They really, really need to start making some professional grade lenses for these cameras.
