We’ve already had some discussion about the DD here and here. At first, that’s what I was wondering as I examined the photo, but as Erno pointed out, my clue-reading wasn’t very strong. 
And even if that were the case, the DAC still needs to be upgraded if one of the “new Upsampler” capabilities is higher resolution playback.
Again, as we say a lot here, don’t get me wrong. I would love a more muscular Upsampler and DAC without having to replace my current stack. My bet is still that they will be in the form of a Vivaldi successor/replacement/topper. On that last thought, it’s not inconceivable that Vivaldi could become the #2 in the dCS lineup, not replaced, but demoted. I don’t expect that. The clues all point to a new top tier DAC & stack. Vivaldi got Apex-ed. then Rossini. And now it’s happening to Bartok. So what could conceivably be “the next generation” other than a new top tier stack? When I bought my Vivaldi stack, I actually expected this possibility to be sooner than now.
I’m excited to see what dCS do here.
