Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
They could capture with a DALSA Origin, RED ONE (when it becomes available), Vision Research Phantom 65. These are all 4K cameras and I think theres a few others about or in development. Not for your holiday videos however ;^)
