According to PhotoRumors, Sigma is working on 2 versions of the 12-24mm lens. One will be an Art series lens and the other a Contemporary series lens, this is the same sort of thing they've done with the new 150-600 lenses.
Sigma currently makes a 12-24mm f/4.5-5.6 DG HSM II, and a constant aperture Art version of such a lens would be very sought after if they continue with their aggressive pricing.
More to come…
