I didnt either until I stumbled across them while searching for tyres! From what I've read, the main thing I picked out was that they have improved the shoulders to give better wear. But I guess only time will tell. I think they'll have to do well to beat the Falkens that are currently on the back of my 330d as they were on there when a bought it and have lasted really really well considering I have 673nm at my disposal! I think they've got over 20k on them so far which I'm very impressed with.
