It's most likely going to be four seasons, if the sight of the ocean in the teaser trailer is to be taken as fact. It's not specified, true, but some simple calculations make it obvious. It's pretty certain that Shingeki No Kyojin is at its final arc, since it's been predicted that the manga would end in late 2018/early 2019.

Who knows, though. The 4th season might end right where the 106th chapter did. It just seems like that kind of scene. But if we're to consider that there are no more than 10 chapters left (probably less), it seems way to short too fit so few chapters into one season.
