DLP has been a standard for a long time in the commercial cinema, and for good reason. Sony's attempt to uproot Barco, Christie Digital and NEC failed miserably. LCD and lCos are not even on the same playing field as a 3-chip DLP projector. I just read a few days ago that Barco and NEC was going back to TI DLP for all there light engine processing. Christie only makes DLP cinema projectors, they offer some projectors with other than DLP, but not many, and none for the big screen. Barco experimented with 3lcd for it's 6P laser projector and it failed to generate the picture the TI DLP produced.
When Sony came out with there Silicon X-tal Reflective Display(SXRD) on there pro SRXR320P projectors they even had the balls to compare a SXRD against a 2K DLP Christie. SXRD is 4K, that was a lame attempt by Sony. 50 out of 70 preferred the DLP over the SXRD that was at the cinema screening. Go figure.

Sony does not have a cheap business model with any product.
