What Compu_85 said. The brand names 4-Motion and Quattro have no bearing on whether it's the longitudinal Torsen system or the transverse Haldex system. The only thing they indicate is VW or Audi. If the AWD system is on an Audi, it's sold under the Quattro name. If it's on a VW, it's sold under the 4-Motion name.
For example, the Audi A4, A6 etc. use the Torsen system, the Audi TT uses Haldex. All called Quattro. The VW B5-B5.5 Passat was Torsen, like the A4 and A6, although the B6 Passat is Haldex IIRC. The VW Golf R32 is Haldex They are all called 4-Motion. Same systems in all.
I also agree that it'll be the Haldex system if we see it. Some would argue that for the sake of inclement weather, the Haldex system has a leg up on the Torsen. No doubt that'd be a hot topic though, lol.
But to answer your question, no doubt it'll be a 4-Motion system,
