It's a two page summary. Note that this, and the accompanying press conference (with professional PR team) are it. That is the entirety of the details they have released.

The final bits of text indicate that the full study is to be published as soon as it's available.

All statements made in the paper are marked with "vorläufig", which translates to preliminary.

Considering the gravity of the situation, I don't think it's bad to provide preliminary results, but that's probably highly debatable.

I think it's absolutely crazy and irresponsible to do a press conference on a paper that you haven't even released a preprint of. I really hope that there aren't any issues with the actual publication, because if there are, they're going to cause a great amount of damage to scientific credibility, which so incredibly important right now.

I agreee, but I find it highly problematic and even dubious that it’s now taken as factual by the mass media in Germany.
