As seen on Fatbike.com, Carver’s released a full-Ti, full suspension fatbike.
This one is a Rohloff, with a Riise Racing fork and a X-Fusion shock.
The plot thickens. (I wonder if it’s flexy). It says clearance for up to 5″ tires, but that must be with a Lefty. The Riise is built around a 120mm hub, and looks pretty tight with the wheels shown (Marge Lite or Rolling Darryls…60-82mm) and Nates. It doesn’t look like it would clear a 5″ tire.
