In guess it is not only the RTVR report, as others have pointed out, and I have not seen any single good review so far, which is different to e.g. VR Days (and I was in Amsterdam too and impressed enough to back the 8K(X) and 8K). So there clearly is something wrong with the V5 prototype they brought along, which is a pity because we all had little news on the progress since KS ended.
And I was convinced of the 8K during my hands on, but it still had the convergence thing going on nevertheless. But it was not that disturbing to me although I did notice it, and I was convinced this would be dealt with by adding the IPD adjustor, so considered it a flaw of the prototype iteration and something they would surely resolve in their next iteration. Well, that apparently has not happened. The big question now is, is this a bigger issue than I thought ? Is the level of discomfort or distortion caused depending on the individual‘s IPD ? That would probably be good news for me, because I found it okay-ish if not ideal; but for others that may kill the experience.
So I think it is fair to be somewhat concerned about the state of the 8K, but not to now conclude that it is trash and will never be a good product even if it takes them a few months longer than we hoped for.
As to the RTVR review: put yourself in their shoes. They are to review a near final prototype, which you then expect to only have minimal flaws, if any, at such late stage before release of the product. And then you experience a number of really noticable flaws. I think this is where then the effect of having used very bold promises (8K, delivery starting in Jan, controllers to be added by March which only exist in concept drawing at the end of KS, promise to add eye-tracking, wireless) start to haunt Pimax because the reviewers, who talk t many other VR companies may start to feel that the guys just promise way too much and then come to a show CES weeks before scheduled delivery with a product which has a whole list of deficiencies to address. I do see how this can then kick off a negative review, to be honest.
I certainly still have hope, because at VR Days I felt it would even be not ideal, but acceptable as worse (not worst) case scenario to get a product more or less like the V2.
