With IBIS coming and their IQ being so close – cost, weight, size, and filter expense are the only remaining and substantial differentiators.

Like you said, f/2 is THE reason to choose the 28-70, but it is difficult to underestimate the difference that makes in the image character. The 28-70 @ 70mm/f2 renders like a Zeiss prime, which is quite astonishing for a zoom.

My 28-70 was a tough return, but I did so because I just didn't think it offered a close enough rendering to a good 1.8 prime (let alone a 1.4, or 1.2).  I sent it back on the hunch that id' be happier with the IS zooms when I needed a zoom, and primes when I needed speed. I'm happy I went that route, as the 15-35, and 24-70 that Canon has released are fantastic.

I think the only real way you'll know for sure if the f/2 is something that will impress you, is to use the lens.  Some folks love it, with good reason.  I feel it's an impressive design, but for just about 99% of scenarios where I'd be shooting close to f/2 I'd rather use a fast prime that would almost certainly give me a superior image.
