You know what, screw Mitsubishi for doing this. They've never come out with anything to match my Samsung LED in price/performance, and I'll be damned if I'll ever invest in anything from them now or ever after this. Its one thing to completely drop a technology, like Samsung has. Do they have an obligation to give us a converter box? No. Would it be nice if they did? Yes. But TI and Mitsubishi allowing, and in fact in Mits' case FORCING my 2 year old set to be a 3D orphan when it was marketed as being 3D is B.S. They are going out of their way to break it. Mitsubishi is the one that is still pushing DLP and all this does it put another nail in the coffin in RP DLP for them for future buyers.
UMR on HDR vs 4K: The benefit of greater saturation and luminance capability is...not very evident in all images unlike more pixels which can be seen in every scene.
