I think so too and I guess this will be the modus operandi in case of an early ending to the season. I would still promote the first two teams from 2. Bundesliga though and play next season with 20 teams.
As I mentioned earlier, this could give us some opportunities in the outright market betting. I checked some bookies and most don't have any or a lot of outright markets still up. Tipico has quite a lot of bets, the problem is, you can't really parlay them, which I would like to do to not have too high stakes. Nevertheless, there is one parlay that gives very good odds:
SC Freiburg under 40,5 league goals @8.50
Leipzig under 66,5 season points @2,90
Parlay @ 24,65
The T&C from Tipico are not very clear:
