There's been a picture of the external version on Pangolin's facebook page for a few days now.
It appears to show DMX Out / In and ILDA Out / In and Rj45 + colour screen, SDHC (?) and some kind of mode button with RJ45 data indicators and some kind of indicator over the mode select button:
I'm guessing the fact that there's DMX included means an end to needing an Entecc interface.
