I think since all of the patches on steam have been BETA's, it is unlikely that we will see a full patch until most of the game breaking bugs are stamped out. This is the latest hotfix (http://steamcommunity.com/app/388410/discussions/0/496881136927436269/):

BETA Patch November 18th 2015 - Archon Crash fix & General Stability fixes

We will of course continue fixing Darksiders II Deathinitive Edition.

Here is a guide on how to access it:

So it looks like there is still quite a few serious problems even on the steam release up until recently. It might not be out for quite some time on GOG. I would put this game back on the shelf and give it a month before coming back, since it seems even if we were to get a patch now, there is a decent chance it wont be a stable experience in any case.
