We now all know that the BDA has given final approval specs for the upcoming 4k Blu-ray format, and of course the new players will be backward compatible with current Blu-rays and DVDs. We also know that the new players aren't set up for 4k 3D, at least not yet, but here's my question: Will the new players allow me to see my 3D Blu-rays in 3D, or will I have to have a separate 3D Blu-ray player attached to my Home Entertainment center?
I will also be interested in seeing the first catalog titles released in 4k, quite probably by the Holiday shopping season this year. On occasion I've read rumors that 'Lawrence of Arabia' was going to be one such title. Among modern releases there is no doubt that 'Star Wars: Episode VII' definitely is coming in Summer 2016, and Marvel's titles will certainly hit store shelves.
So bring it on. As I've stated elsewhere, I've just bought the 850c, and it's waiting to strut its stuff!
