I've still got a 2013 plasma with 3d and while you lose half of the horizontal resolution (the image is stored twice side by side) it isn't really noticeable in most 3d blu ray movies. Streaming services lose a lot more sharpness by compressing the heck out of their movies.

Most blu ray players (even the 4k ones) still support 3d since the only thing needed is to pass the image with a '3d' flag set. The rest is up to the display.

Personally I'd like to add the movies "Hugo" and "The Martian" ;)
