Dennis's development is unique, characteristic of very strong storms. I remember tracking supertyphoon dianne in the west pacific last year, and it almost magically developed bands out of thin air in the shape of idealistic tropical cyclone. Must be a by-product of strong pressure drop over a symmetrical area; almost like Dennis. The dennis/cindy track(s) kind of remind me of a bonnie/charley situation to a lesser degree. The poleward axis's of the subtropical ridge will maintain the speed (16kts NWestward). The only inhibiting factor will once again be its proximity to land.
