[Update: Depth was launched August 31. According to Mark Christiansen, "Depth does just what the name implies, easily extracting 3D depth data for use with Digieffects plug-ins such as Camera Mapper, Atmosphere and Falloff Lighting ... I especially like it for lens effects that can use depth information to create beautiful cinematic bokeh blurs."]
Digieffects seems to be breaking off another plug-in from its legacy products with the launch of Depth, a filter found in the old Buena Depth Cue package. There's no official pricing yet, just Vimeo video partly via Lester Banks:
