Some people have gotten their tickets, some haven't yet. At least one is expecting them on Monday. If you get to Thursday, and you still don't have your tickets, that would be extremely annoying and a ridiculous mistake by the organization. We're not there yet.
Not getting tickets by the first game? Bad mistake by the business, but you can still get into the game. Not getting an email before the tickets are delivered? Yawn. The drama is too early.
Worst case, if you don't have your physical tickets, and you don't have a cell phone, and you are actually planning to go to the game, you still can.
