The investment could be made now, but alas, Cameron is the only one that seems to want the investment to be made and probably has to put up his own money, not the studios to get it done.
Sadly, Cameron and Christie Digital are not moving toward autostereoscopy
(glasses-free 3D) with the Avatar 2 movie, but to better Laser projectors
, with the same polarized glasses we know, but with brighter images, maybe HDR-like, Wide Colour Gamma image presentation. Maybe some HFR in selected cinemas with those better Laser projectors.
Autostereoscopic Avatar 2 is just wishful thinking at this time.
I'm sure that Cameron would like to present his new movies in an autostereoscopic cinema, but right now there is no sign that this will be possible.
Why? Because there is no known autostereoscopic cinema, no proven technology that can present glasses-free 3D images in a cinema sitting, on a very large screen, with many peoples spread all over long distances, left-right and front-back, on a slanted floor.
What we have now are small (around 55") autostereoscopic screens (LCD/OLED based) that can maintain autostereoscopy for smaller distances and smaller audiences, like Ultra-D or old Philips WOWvx displays. Most displays have sitting limits, like 46 (Philips WOWvx) or 64. Ultra-D displays have 26 "zones" for now (4K panel, on an 8K panel maybe more zones).
Even microLED Cinema screen from Samsung is using the same polarized filters and classic passive glasses to display the 3D image...
