As a stills photographer, I have zero issues with the 24-70ii not having IS. I guess that aside from videographers, those who want an IS version of the 24-70, lives too much in theory and do not spend enough time out there taking photos.
My camera doesn't even have a video mode, but I shoot in low light a lot and it's incredibly useful. Just today, I took a bunch of handheld portraits in low light between 1/15 and 1/40 shutter speed on my 100mm IS lens, without IS there's no way I would have been able to get anything useable in that situation. When I rented the 35mm IS I took a portrait in almost nothing but moonlight that was around 1/4 second that came out great. Sure you could use a tripod or a flash, but that's just more stuff to always have to carry around just in case, while IS is always there.
And I'm not saying the 24-70 II is not a worthy replacement, but that there were rumors of it having IS before it was announced and people were asking for it, and I suspect Canon decided to hold out on a f/2.8 IS as a business decision. I'm not the target market for such a lens so my opinion on it doesn't really matter, just an observation.
At this point after seeing what they did with the 35mm f/2 IS and how compact and inexpensive it is, it's difficult to see any legitimate reason Canon couldn't include IS in the new 50mm. I think they know people want a replacement to the f/1.4 so bad that they will take what they can get, IS or not it will sell just fine.
