There isn't anything available yet as the car is too new for general replacement shocks. For a couple of years (especially with a "family sedan" like the Passat) the options will be either springs or full coilovers. Bilstein has a Sport shock (shorter case to accommodate lowering) in Europe for the latest German Passat, but there's no guarantee they'd fit, and Bilstein US might not be willing to import them.
By the time the stock struts and shocks wear out, Bilstein and Koni will have several options, and Eibach and H & R will have their ProSystem and Cup Kit matched spring/shock (shocks for both made by Sachs) setups.
The next step may be for someone to see if a B6 Cup Kit would fit.
