There isn't much info for this year but I would recommend checking this video about last years Master League to get a good understanding on what to expect.

Honestly I am not too crazy about Master League myself haven't been in a looong time but I am hoping the adaptive AI really helps change the way games are played.
Also no Bundesliga but with option files people will add it in.
