However, Alex did say that the series would only document the events of one Summer, so a season 3 about next Summer wouldn't work.

If Gravity Falls continues at all past this season, it'll either be a movie or some sort of arc with time travel, thus keeping it in the same summer. I'm not betting on anything as of right now, though. There's too much uncertainty to be sure. I agree with every thing you just said!
