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:
More information.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.
