I've thought about that a lot too, in a sense being able to buy these new would be a godsend for years to come.
I know the PVM/BVM factory still exist, it first stopped doing stuff in 2004 but was later reopened in 2007. Manufactured until 2009. Still there - most likely.
One could most likely pull one like the
Impossible project which is the story of a dude that actually purchased the last Polaroid factory when Polaroid announced they would exit the business and have been happily gaining track of the technology ever since.
But I don't have the money, we don't have the money. Nor the engineers, nor... But I'd love to see it happen.
It's not just CRT's that are missing, it's a brand focused on gaming altogether. Imagine a 55" or 65"screen with 640x480, 1280x960 or 1920x1440 (these HD variants are perfect multiples of SD so scaling would be perfect 1:2 or 1:3 but could also be used as HDTV's with black bars), of course there could be a market there, you could even throw scanline options in for free and obviously a lot of ports, Scart, S-video, VGA, component (you could even throw something like an integrated xrgb mini).
I'd buy.
It's worth being said that at 60.000 hours minimum until half life some of us have gaming monitors for a lot of years since they are not to be used for anything else. And if it hits half life you can try and pull a lazarus on it with voltage changes and the like, for real desperate people I guess.
