Long Time Ahead

It is not easy to understand why some things have to be decided so far in advance. The International Ice Hockey Federation (IIHF) decided yesterday that the 2013 World Championship will be hosted by Sweden. This is cool, but I already knew Sweden can be trusted to host major international competitions. After all, Sweden will be the host of the FCI World Dog Show next year. I just wonder why the IIHF needs to decide upon the host in 2013 this early. Are so many preparations necessary?
