No not really. If we had received Cyan then we would have had BT LE and several other features like more enhanced (whilst not at full extent) camera features, Cortana, etc..
Like I said,
sort of kind of. All the feature of 8.1/Cyan besides firmware update (like your asking for) features were included with the DP.
I agree, I want those features as much as you do but(the camera is a big deal to me too), the DP did give you all OS related features to Cyan/8.1...(you got Cortana, Notification center, pictures in the background of tiles, etc)
Let's just disagree to agree here, Still there is no excuse now why we don't have Denim, it's just a Verizon thing....
