I disagree. I have had a 632U for ~1 year. 3D in its present state has been around for 3+ years, Today, the bulk of the 3D offerings available are animated BluRay movies. I checked carefully when I bought my 80" Sharp, and I concluded then that 3D would either never catch on or would do so at a glacial pace. I see nothing coming in the future to change this situation.
I still find it funny to ask anyone who owns a 3D set, "What was the last thing you watched in 3D" (while preparing for either a scowl, a grimace or a just a lie)
