If one theme of NAB was 3D, the other was video-capable DSLRs. The danged things were everywhere; I saw more people shooting video with DSLRs (myself included) than with anything else.
There was plenty of new DSLR gear to look at, too: the usual suspects (Zacuto, Cinevate, Redrock Micro) has lots of mounting kits, rod systems, and support accessories, and they were joined by the likes of Ikan.
