Things can definitely change, that release and that website doesn't look like some iron-clad guarantee of the format, it's two years away. The travel to Europe for some round robin, and then BACK for the finals does seem a bit excessive for the European teams. I think this is for NHL players only, which I'm not even sure how many can dress a full team outside of Sweden/Finland. I wonder if the compromise is to hold the tournament in one location but have games that start at noon so they're watchable for European audiences.
