Eh, what can they really innovate in that spectrum? They already have the whole 24-xx spectrum covered; they just need to update the 28-135.
Not really, on both counts. This looks like Canon is trying to build some new low-end kit lenses for convincing people to switch from crop-body cameras to full-frame cameras. If you want to get the low-end consumers to move from EF-S to EF, you need a lens that will feel similar to what they're shooting with now. Lots of folks shoot with the 18–55 kit lens, which is angle-equivalent to about a 29–88. For those folks, a 24–85 lens is a pretty good match—wider at the wide end, and only slightly wider at the long end.
The whole point in a kit lens is for the photographer to start with something cheap so they would get a good idea what lens they want to spend good money on (wider and/or longer, faster, etc).
In other words, I doubt people would start with APS-C + 18-55mm and say "oh, I like the lens, we just want a bigger sensor", and fork the cash needed for a 6D + EF 24-85mm.
The scenarios I see are
A) APS-C + kit -> upgrade lens -> possibly buy more lenses -> upgrade to FF
B) Cheap FF w/ EF 24–85 in the kit -> upgrade lenses.
In the later case, a cheaper than the current 24-105mm kit would make it easier to buy FF as first camera, skipping APS-C cameras altogether.
