I will be speculating but I think we will see a German team in the KHL around 2021-2022 or 2022-2023 and that team will not be in Berlin nor in Hamburg and will not be a newly created team, I think the team will be Red Bull Munchen, their new arena (SAP) will be finished by the summer 2021 if I am not wrong, and I don't think that the financial chapter is a big issue for Red Bull GmbH (the owner of the team). I also base my speculation on the fact that the DEL will soon be too small for them as the BBL is too small for Bayern Munchen Basketball team (they have now wild card for Euroleague), as well the football bundesliga is too small for FC Bayern Munchen and they have always been linked to some kind of European Super League in football, so it will not be really surprising to see the hockey team of the city joining a closed league. Moreover Lowen Frankfurt applied to play in the DEL next season, so I think they will sooner or later join the league and I think they could replace well RB Munchen in the future.
Very good analysis, I agree with your reasons.
You are very right that national hockey leagues are too small for some teams. There is simply no growing potential anymore. Hence, the CHL was created. Still, the CHL is not that league, which European big market clubs need.
We have always heard how the European clubs are interested in the business side if considering the KHL. The SAP deal is a clear signal for them. Business on the 1st place.
The model of a closed league within Europe, which has been offered by the KHL recently, is very attractive for clubs like Red Bull Munich or other big clubs. They would travel only within Europe, perhaps one or two trips to Moscow, St.Petersburg or Kazan/Ufa.
Let's speculate. If the KHL did a division of 5-6 German/Swiss clubs, Paris, Slovan-Prague-Vienna, Jokerit-Riga, it would be enough.
The biggest DEL´s problem is a disparity when you have great teams with great venues (Berlin, Cologne, Mannheim, upcoming Munich) followed by teams with very inferior infrastructure. So, top German clubs lead the European attendance figures, but the overall DEL attendance is not so impressive. Even though, it is still 3rd in Europe. Big market clubs need stability, so a closed international league.
