V/T will keep winning everything as long as they remain injury-free and motivated. I don't see S/K as being huge threats even though they beat S/S in Sochi (due to S/S's own mistakes). Chinese pairs could challenge with their high-flying quad elements, but it's a big "if" in terms of how successful they are at those. Savchenko/Massot looked promising in the videos, but they need to sort out their finances/representation problems.
Ice dance will probably be W/P and B/S for a season (I don't think C/L are going to win Worlds again...). But I can see B/S being overtaken by the new Russian teams in a year or two.
