If you had posted this in the video sub-forum, there's an issue that would have been brought up that's only been alluded to here depth of field. Focus-pulling on Super 35 is hard enough as it is, and increasing the resolution and propensity for shallower depth of field will only make this harder. And you can add to that that 3D and shallow depth of field are not friends. It's not just a headache for focus pullers but also a literal headache for most viewers.
To add to the VFX argument, have a look at
this article about rendering on Avatar. What do you reckon would be their response to you asking them to model and render everything at sixteen times the resolution tomorrow?
Although your point and attitude have been shifted throughout the thread, I still don't think you're properly appreciating just how much goes into making and distributing a movie in particular how small a part the camera and projector play in practical terms.
Keep chasing that rainbow, but if you genuinely think it's as simple as swapping out the cameras and projectors, you're yet to realise a rainbow is not something you can actually grab a hold of.
(Oh, and check out the
Phantom 65. It's been around for years.)
