Christie is duking it out with the venerable Technicolor in the digital projector war. At issue: whether a 2k projector is enough resolution to make going to the theater more attractive than watching at home on HD:

the 2K digital standard is barely higher pixel resolution than regular HD video, 2048×1080 rather than 1920×1080

As usu, HD for Indies and CinemaTech are all over this like RGB on pixels.
