I would say its impossible to guess, but if I HAD to, I would say no. Winning more than 2 tourneys in a row is difficult, never mind 3 MORE in a row after 4 straight, hard to to. Especially with tons of players making the NHL long before their eligibility in the WJC runs out.
It's possible with the next couple WJC scheduled exclusively in North America. However, I think Canada will have a much tougher go of it as the relative talent level coming out of Europe seems to be miles ahead of where its been the last few years.
