I'm confident that most of the issues seen are just initial issues, which occur on each and every platform. There are plenty of potential issues, there is no way to deny that. However considering that the whole software- and firmware-stack was basically rewritten in less than four months, my personal opinion is that AMD did extremely well, regardless of all the minor issues. If it was up to me, I would have had postponed the launch by 1-2 months. This would have given both the ODMs and AMD to refine their software and firmwares to a point where most of these issues would have no longer existed.
Regardless, I am certain that all of the minor issues will be ironed out, within the next month or a two. I don't believe there are any actual hardware issues in Zeppelin.
Aside from just fixing the actual issues, I'm confident that the performance will somewhat improve as well
This is my personal point of view on the subject.
