I am very excited about this projector in terms of the possibility that the technology will take off with Sony and especially JVC. We have been told that with a laser light source there is not the added bonus of not replacing your lamp every year or two, but potentially having better black levels, higher local contrast levels, and expanding the color gamut. These seem like they will have a much bigger impact on picture quality than just resolution. The Sony's first projector to do 4k was $25,000 to $30,000. This comes in at $8,000! Hopefully we can see some improvements in picture qualities mentioned above, or it is at least as good as the current best offerings. Like I said, I am excited about this technology.
The only issue I am concerned with is using a laser light source. In a low ceiling mount application do we need to be especially careful of looking into the light? This would be a big concern with kids.
