For my two bobs worth:
I actually preferred the faders with the coloured center-line, maybe have the both as an option in the mixer layouts?
You have a very nice theme here that would be very easy to spend many hours in front of. Hell just on what I have seen so far, I'd even pay some bucks for it!
The new transport bar is really slick, very neat and just works.
As for the MCP layout I am in preference for the one shown in the full size photos with and without icons.
Having the outer rings that moved with the position of the knob would be the icing on the cake - you'd have all my money then
