Maybe I've missed this discussion. I read all the reviews and check all the manufacturers web sites. It seems like the only 4K options in projectors are sony's 4K units or everyone else's 1080p units with some form of pixel shift technology. I've seen the JVC projectors in various showrooms, and they look great....but the engineer in me just can't spend the money on a projector that is based on 1080p display technology. Just wondering why Sony is the only manufacturer (that I'm aware of anyway) to offer a 'true' 4K projector when everyone else is on the pixel shift side of the fence. Is it some type of patent? Are manufacturers holding out till there is finally consensus in the UHD bluray format? Just curious. I'm realistically a couple years from making a change but will definitely be buying 4K as my next projector.
