Flew through SXF last week. Inbound, bus to a new-ish looking passport control and baggage claim. All with BER branding.
Outbound just as dreadful as always. Overcrowded and too hot, additional lanes of security opened in the EZY terminal, but still queuing longer than at MAN T1.
In terms of the new terminal, even 2020 is being doubted:

A LH employee has (perhaps flippantly) suggested it should be knocked down:

Also from the same article, the passenger info screens installed prior to 2012 are due to be replaced as they’ve reached the end of their lifecycle.
This story is simply astounding.
