I am about to buy a 24-105mm mainly to take video. I don't really see the purpose in getting the 24-70mm f4L IS unless reviews say it is just significantly optically superior in every way compared to the 24-105mm for its range. I think the price of the 24-70mm IS out the gate will be my main deterrent from the new lens and if Canon follows their 70-200mm formula, I should probably just wait for the 24-70mm f2.8L IS because we all know that's what everyone really wants.
If someone like Sigma can get their 24-70mm OS out the door before Canon does, I'd happily get that to complement my 70-200mm OS. I had my eye on the Tamron, but I'm hearing a few issues like onion bokeh, focusing issues and random lens error lockups.
