Looks like the Rodenstock Macro that they were using (which was nearly $10k!) has been discontinued. In its place they have identified a series of Linos Inspec optics that come in various forms and focal lengths. They're selling them all but targeting one in particular as most useful for 135-4x5.
They've also released their helical mount for X Hasselblad cameras so I'm really hoping to see multi shot (a must for scanning IMO) come to the X2D2. I'm a user of their 3 way leveling base and RPS500E platform and I've been extremely happy with it.
