Lots of 65" 4k TVs from most manufacturers.
Several were demoing the latest 3D glasses free from either stream works TV or Dolby 3D. Dolby offered the larger size screens but the Streamworks seemed to have the higher picture quality, IMO.
Sony disappointed with their 4k models as they now switched to a much thicker base wedge cross section design. This means it will not mount flush to the wall like a picture. Image quality was quite good however.
PS4 has 3D blu ray support in the works with software update.
No new 3D camcorders. Everything this year was 4K camcorders.
New Sony innovations: short throw projector technology.
Table top touch screen projector. This projects from the ceiling to the tabletop for a touch screen control. For example, you could play board games like chess with this system. A mirror on the wall that changes to a video display when you approach it.
