Hi everyone, remember the new Sanyo review has not been proofed yet. I want to be clear about one point. I've said in the review, that I cannot tell whether the improvements in color handling that I noted, were actually improvements, in the 4000 from the 3000, or firmware updates done as a 3000. I fully stand by my statements that the Z4000 I received after calibration definitely was slightly improved over the 3000 we reviewed. -a
