As far as I can tell, this pretty normal for Bethesda. And expecting an ETA on when the issues will be fixed is kind of ridiculous. Game design is pretty darn complicated, even with games much smaller than Skyrim so there's no way of knowing if or when the issues will be fixed. Beth's bug testers might well fix one issue only to create five more. The final patch for Skyrim Classic introduced the lip sync bug which they didn't fix until the remaster for instance.
