My interest level will reflect the interest of the players, and due to the lack of true best on best tournament in the last decade, I believe they will be very motivated.
It will take some time to build, I actually forgot this was going to happen. But in the end Sweden vs Finland and Canada vs US in a true best on best is something to care about. It will be used to settle hockey arguments for some time.
Btw. If Russia participated at this time Sweden or Finland would never join them, and if they did I'd never watch another second of the swedish national team in my life.
