IF Cinema Black (not to mention the 4th HDMI port) had not already been included as standard features in their comparably priced 2011 "D" series line, then I might be inclined to agree with you. The fact that they removed both of these items from their 2012 models in what appears to be a fairly obvious cost-cutting move, but are bringing them back in 2013, speaks volumes.
If history is any indicator, retail pricing of the 2013 line will mirror that of the 2012 lineup. So, for us to gain some (but not all) of the features and benefits of what the new 2013 model has to offer, Samsung is giving us an opportunity to shell out another $300-$500 to them and still wind up with a lesser quality TV. As always, YMMV. But, for me, no thanks!
