I would also like to add that even in cases when Germany has a weaker roster than Switzerland it is never a piece of cake for the Swiss to beat them, the games are always 1-2 goal games and sometimes the Swiss seem to struggle against the Germans at the junior level just as Slovakia struggles against Switzerland.
I would say that the chances of making it to the quarterfinals are about equal for all of Germany, Slovakia and Switzerland and very small things can make the difference between who will and who won´t make it, but it will be interesting for sure. Stealing a point or two from Finland by one of these teams might also play a role. We will see, but I think that this last few years should have taught us that noone is guaranteed to make the quarterfinals even a team like Finland yet alone a team of the level like Switzerland. Doesn´t mean they won´t make it though. For obvious reasons I hope they won´t though.
