Nope, never heard of them. Besides, I have reviewers that I trust implicitly already on the ground in Vegas and will be interested to hear their feedback when they get home.
As for the "doesn't concern you, what does..." I can say that nothing on these forums concerns me one iota. You see I backed a Kickstarter project with a significant sum of money. Since I went into this arrangement with the understanding that I was providing Venture Capital to grow and existing technology business, I considerd all of the funds as gone the moment I funded. Gambling is a risky game, and one should never gamble more than they are prepared to loose. Kickstarter is gambling to the nth degree, so the rule applies twice over.
Once they announced delays in the schedule I knew that there was a possibility that things were going to go badly at CES - so the current forum panic is no shock to me. I know that any visionary technology project WILL have setbacks and false steps forward, it is the nature of the beast. As such I am willing to wait for Pimax to finish the show, compile feedback, assess priorities, and address the forum about the March timeframe that had been presented earlier.
I am confident and content with the pace of the project at this time. I will reassess my position at a later date.
