There is, what, only one patch...
There've been several, they're all just put together into the latest patch...
It would be nice to have another patch, but they can't keep patching - especially not if there's no publisher to finance it. And they do have Divinity 2 and yet another secret project ahead of them after <img src="/ubbthreads/images/graemlins/riftrunner.gif" alt="" /> (which will of course be better and less buggy! <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> ) ...
So, maybe they will, but if they won't, I can't blame them.
