Absolutely, but that was already stated before my post. I was simply addressing the likely screen requirement for 120Hz 4K L/R passive 3D. That's something I'm looking forward to as an upgrade over my current JVC or potential Epson.
For some, spending $10K to get 4K and laser makes sense. For me, I need improved 3D to justify the upgrade since there's no commercial 4K movie source and my projectors rarely outlast one or two lamps before I sell and upgrade. For $10K, the CR/Blacks must be at least as good a JVC and the 3D better blow just about anything else out of the water. I also figure that by the time Red starts shipping these, Sony will be selling a VPL-VW1000 lite for less. Red needs to hit a home run to succeed as a newcomer to home theater projection and that's means great 3D, not just 2D. If I can get that from a Red and new screen, I'll buy one and change my screen.
