I believe that 3D will be around for the next 5-10 years, enough time to give Holographics a chance to catch up.
Once Holograms are able to be used every where, 3D will fade and everything will be holograms.
Holographic movies, Holographic advertising... and the list can go on and on.
This is going to be an exciting time. There is no doubt that 3D is on the rise and technology will only grow from there. I cant wait to see what the future holds but for now we are going to watch 3D become one of the major driving forces in the world today.
Almost ever major company has a 3D advertising campaign already underway or in the works. This will be interesting to watch how everything develops and plays out.
