Some of the projectors we use to use in concerts & live events dwarf that thing in size & price. We use to double-stack Barco HD-18's & R-20's on scaffolds 10' high for 30' screens. Those projectors are around 250lbs each & worth $100k each. His system is definitely not obsolete, since they just recently started selling cameras that approach that resolution...Other than IMAX. Cool, but I wouldnt pay that much for a theatre.
