I haven't done much market research in that aspect yet but we currently sell our industrial 70" display @ around $9-12k/ea depending on the configuration (ie type of metal shell aluminum/stainless/carbon-steel, ethernet support, protective polycarbonate screen in the front to prevent damage from industrial machinery). However, I expect the consumer grade to be much more cost effective considering the sizes in demand would are much smaller (32-40"). Since I have more experience in sheet metal design/fabrication for the enclosures, I still plan on building these TVs inside a metal shell (specifically aluminum) instead of a plastic housing like your standard Samsungs/Vizios. I'm open to market consensus as to what is the most favorable price point for the size.

will they retail globally?

We ship globally to our customers right now but I believe having a distribution channel for global retail would be much wiser. I'm definitely open to it once we get to that point.

FWIW, I'd be looking for a 65" or larger, but to be honest those prices probably wouldn't work for me. But regardless, I'll look forward to seeing your Show HN when the time comes!
