Thanks for the new pics. While maintaining the basic design, it does look like they've changed the top tube as well as the seatpost clamp. Seems odd they would continue refining the older design in parallel with the monocoque. Sort of splits the R&D and fabbing costs between the two, driving up the unit cost for both.

Yes, did notice the BB7s. As they are higher end mechanicals, could be that R&M would have wanted to use upper end hydros, which would probably have driven up the cost. Could also be that hydros just don't work well with this type of fold.
