I use the first 10 minutes of Underworld Evolution as one of my benchmarks. The HW50 is an improvement here in this area (vs the HW30) and looks very good. I'm not entirely ready to give up my RS55 just yet, but we are getting closer and I think it's going to satisfy the majority of new owners.
I've seen RC inside and out and know the pros and cons on the HW50. Now i'm curious to see how RC compares with E-shift 2. Hopefully we're just a few weeks away.
Overall though, the HW50 is a great all around projector and would certainly choose it over the previous HW30.
I'd like to see all the new features (brighter 2D/3D, RC, better 3D) in the V2.0 of the VW95 if it was actually released. That's the projector that would give the new JVC's a run for their $$ since it would have better (than the HW50) native contrast, better lens, full auto shift/focus, etc.
