I will not be surprised if eventually Bayern Munich looses out on this seasons Bundesliga title but with leipzig, and Dortmund I do not have a particular, they both frequent the top four positions on the table often, it will be almost like a norm if it happens that both of them eventually finishes top four or even either of them but with the title Leverkusen even looks more viable than this other two for the title.
And it's too early to jump to a conclusion. Leipzig and Dortmund did not do much last season, and this season, they might wake up, and I don't see the reason why you would say Leipzig and Dortmund are better than Bayern Munich, as for me, I don't think so, don't know for this season yet, but I have seen something different at this point, because there is there a lot of things you can not say when it comes to a new season and eipzig, and Dortmund and leverkuseen and bayern are like the strong clubs in bundesliga.
But things might change if Bayern Munich fails to do better than last season, that is, things that will prevent them not becoming champions this season, because a lot of clubs have made a lot of changes, so they have reduced the chances of Bayern Munich winning, so much drama to come this season.
