Just came back from visiting CES yesterday. I only had a day there, so there was no time to get detailed info, but Canon, Sony, Nikon, Pentax, Tamron, and Sigma were all well represented.
The Canon "booth" was massive and impressive. They had seemingly all of there top-of-the-line hardware available to demo. Rows of super-telephoto lenses were lined up on tripods, mounted on 60D, 7D, 6D, 5DIII, and 1DX bodies, ready to go. The whole line-up of video gear was available too.
Nikon also had a large presence and eager to present their best gear. They provided live dancers where attendees could photograph with the available gear. They even provided a "low-light" room where you take pictures to showcase their high-iso capabilities.
Sigma also provided a live model in a studio environment where you could demo their gear.
