Isn't Canon's answer to the 14-24 the 16-35L? Does the extra 2mm make that much of a difference? I have a friend with the Nikon 14-24 on his D800E and he's usually in the 20-24mm range of that lens.
If you specifically need the extra wide end, 2mm makes a huge difference, the shorter the focal length, the greater effect each additional mm makes.
Personally I think Canon is content with the 17/24mm TS-E lenses ruling their WA range, as nice as a super-wide zoom would be, having movements is probably even better. Using only the 24 TS-E, you can stitch together a few shots using shift to effectively widen the focal length, while also having tilt and no bulbous front element.
If your friend only uses the 14-24 at 20-24, he would be right at home using only the 24 TS, and although there's nothing from Canon to compete with the D800E as well, he could just get the upcoming A7r with an adapter instead.
