Remember: Gravity Falls has had hiatuses that have lasted months. Even if it's a terrible thought, we need to take that into consideration. With that in mind, just because Alex said doesn't mean.

Plus, if a third season is greenlitted, then Alex might have problems because you can't just replace your original vision (Season 2b is what Season 3 would have been) with a new one and expect it to be good.

Besides, Mabel clearly said that "summer is almost over", and she and Dipper supposedly leave at the last day of summer. If we consider that, then it's even more probable that the series will end in Season 2. Plus, there can always be spin-offs.

Sorry for being pessimistic, I just wanted to point this out.
