I only buy 3D blu-rays. If its not 3D, I don't buy it. No point: I just rent it on Amazon Instant Video or iTunes. I have a Sony 4K/3D(passive) and its amazing, and a Visio 3D TV which is still good. We have maybe 15 (free) glasses so any number can watch. I will miss 3D, and 3D will be the #1 deciding factor when I buy my next TV.
