For me Leipzig is set to be keeping the head of Bundesliga. For their next match, they'll be facing Ingolstadt while Bayern München will be facing Wolsburg. I'll pray for a draw or even a defeat of Bayern because I'd like Leipzig to get more advance !
This journey is very long so don't keep high expectation from them so we have to wait for few more rounds to get the exact situation, RB Leipzig is on winning streak but it will be very difficult for them to maintain their form in long run, still Bayern Munich is better side and Dortmund is also rising now.
