WTF cares what you think about 3D????? NO ONE! The same people hijack every thread to reiterate their opinion on 3D! This is a new JVC PJ thread, not "what do you think about 3D, again" thread!
The same people said that 3D will hurt 2D performance and innovation. Meanwhile the new JVC 3D projectors (higher contrast, higher brightness, faster panels, roughly the same price too) is just one example of them once again being WRONG.
As far as 2D-3D conversion, that's not a feature that "we" (meaning everyone) want. I've never seen a conversion that looked good enough, and that's done by millions of dollars rendering farms and hours of calculations and software. I seriously doubt a VP inside a consumer grade PJ will do better, and on the fly no less!
