I still think the logical thing to do (which almost precludes it from happening), is for them to split the line. Bring out a 24-70/2.8 II with greater resolving power to match modern sensor densities, and a 24-70/2.8 IS version for those that need it. It's a good strategy for the 70-200/2.8, makes just as much sense on the 24-70. I also strongly believe the 16-35/2.8 could benefit from this as well.
In the f/4 space though, and I'm primarily thinking of the 24-105/4 IS here, while I think that lens could also use an update, I don't see room in the lineup for a non-IS version. In fact I'm really hoping to see a MkII released as a kit lens for the 5D3.
Along the same line, I don't see why there's a non-IS version of the 70-200/4, besides historical context. So maybe I'm just way off base.
