So there's still a chance that D&W would continue skating after Sochi(maybe retire after 2018 Olympics?)?
I think V&M would retire even if they don't win gold medal at Sochi 2014, as Tessa currently has some leg issues.
And as for World title, I think it depends on the results of previous events. If Chan doesn't win gold medal, it's likely that V/M would win gold medal as long as V/M skates without any major mistakes
