Bayern Munich is obviously going to be the winner of the league title every season because they have almost no competition in the league. Dortmund is the only competition that can be considered, but it is not a very credible competition since they are not at the same level as Bayern Munich. And Dortmund is not a team that chases after trophies, they are just a team for business purposes. Leipzig is also not a viable competitor. So as long as nothing terrible happens to Bayern Munich, I don't think they will be dethroned from the league title.
Yes even I dare say that they will come back out as champions. Indeed I have not seen what their gameplay is like for next season, but I'm sure they will do more or less the same as the previous season. If you look at the team squad, Bayern Munich is quite promising with the arrival of their new player. On the other hand, Borussia Dortmund, which is expected to be their competitor next season, has lost their good striker.
