This comes back to the question of "what is rocker"? Is it the lack of (or reverse) camber underfoot, or the tip/tail rise of a ski, or both?
On the "Features" section of that page you point to above there are length/height specs given for "Tip Rocker" and "Tail Rocker". From some measurements I did recently on a few different older skis it seems "traditional" tip rise (tip rocker, if you prefer) is approximately 140mm/50mm. So based on that the 2011 Sultan 85 does technically have an early rise tip since it's listed as 180mm/58mm. Remember, 2.54cm=25.4mm=1inch. 40mm is about 1.5". Not much, really.
The "Tail Rocker" of the Sultan 85 is given as 95mm/28mm, which I believe is in line with what traditionally might be called a "partial twin tip", as a full "traditional" twin tip tail would be the same as the tip, 140mm/50mm.
This looks like another case where marketing is just shoehorning the "rocker" label in anywhere they can. However, at least the Dynastar site is giving those tip/tail rise specs for the ski, which is helpful. The other missing specs that would be nice to have at a glance would be "camber underfoot" and "running length".
Ultimately as SJ pointed out elsewhere all that really matters is how a ski works for *you*, but I think just as with ski length and tip-waist-tail measurements having the other specs listed wouldn't be a bad thing now that everyone's talking "rocker".
