I think 3D will take off this time as the technology is mature enough to deliver. Projector route for me in a 1-2 years depending on the solidity of the road map.

I agree. If 3D Blu-ray is successful, i also will upgrade my projector to a 3D capable one. I'll also need a 3D capable media player of course, when they reach the market.
I think silver disc spinners are a dying format.
After 3D blu-ray, my guess is movie/music media will be purchased on a USB memory stick or similar with the 3D movie/HD music on it.
