Both of these projectors are three panel LCoS technology. The VW60 relys on a dynamic iris to help it achieve its best possible black levels, while the JVC DLA-RS2 manages even better black levels, without gimmicks.
Both have two HDMI inputs, and both support HDMI 1.3. The JVC RS2, however supports Deep Color - one of those "future" improvements we can expect on Blu-ray discs, for better color handling. The Sony, unfortunately, does not.
