Just thinking out loud here, but I wonder if this means that our extra home divisional game next year will be against the Canadiens. It would make the most sense; it would suck to have the Canadiens come to the Garden only once when they could easily come twice.
In fact, the new schedule seems almost tailor made to allow for a third game between two teams in the same division to turn into a "non-home home" game. If you're going to send two teams to, say, Prague, it makes sense to send divisional rivals, and to use that extra game. If you're going to experiment with growing the game by using new locations, may as well make it so that divisional rivals still get 2-and-2 in their home stadiums, instead of 2-and-1.
