The short version:
There was a minister with an undersecretary who prepared a defence review. The chancellor's office didn't like the 'concept'. The minister left office because of a scandal, a new minister came, the undersecretary was fired asap, the new minister explained that he needs to look into everything closely and will not make major decisions/announcements till summer at least. Now we have rumours that there wasn't enough money for the old reform idea and the Bundeswehr might need to shrink to about 156k personnel.
And now the really short version:
It was a good idea to not pay much attention and to not write much about German defence reform in the last months. Nothing came of it anyway.
