Sacred 2 - Addon Still Coming

Ascaron has confirmed the Sacred 2 addon is still happening despite their troubles and the acquisition of (non Sacred) IP by Kalypso Media.  From the official forums:

Studio 2 (subsidiary company of Ascaron) has the licence for Sacred 2 and the devs will continue working at the Addon as they did before.

Kalypso and the other devs will do something different with the old licences they bought. I really wish them good luck with that, they deserve it.

In a nutshell, the Addon is not affected by anything and will come as planned.
