Someone pointed this out on Gearslutz the other day and Steven popped in to explain it:
SSD/Trigger is under Yellow Matter Entertainment (who also work on the Raven and Dragon/Fox hardware) and a different company/team/office location to the guys in "Slate Digital" that work on VCC/VTM/FGX etc. The Slate Digital guys are exclusively working on the AAX updates (VMR is apparently "done" and currently in beta testing)
