850c vs 850d 65"
The D is out now and I don't see a lot of difference, of course they are not side by side either. A Sony VP was in Magnolia and told me the chip was just tweaked a little more. He said it is the same as the B, but the B was produced beyond what they could do with it. They now have focused on tweaking it each year.
But, I am being told that the C is called UHD but is not a "TRUE" UHD. Mag rep said it is capable of receiving UHD signals, but not reproducing them.
I have the C on layaway at $1699 and the D is at $2599. Big difference, but I don't want to be obsolete going in either.
