The bottom line is, with all the talk about "punishing" Saudi Arabia, they will likely try to find some kind of slap on the wrist.
The nonsense coming from Berlin about freezing arms sales, is just all talk to appease the (Turkish) masses.
(Almost) No one wants a more powerful and influential Iran. Saudi Arabia serves an important geopolitical stabilization and counterbalance role in the region. Somehow this will all go away and be forgotten.
