Well, I'm going to have to agree with Cdaked on this one. Even if Sebastian said "address his findings", it means there are issues to be resolved, whether that means hardware, software or both. If the M1 8K were perfect in every way, he wouldn't have found anything to be addressed.
Personally, I'm still glad Pimax is doing this. They could have just as easily pushed the M1 revision out the door and said, "Here it is! We're done working on it. Deal with it.". I'm willing to wait for M2, M3 or whatever iteration until the bugs are worked out. I just hope the list has been whittled down from the V5 and what's left to change consists of minor adjustments. But if not, hopefully Pimax can continue improving it to the point that it's ready for retail release.
