Sony has a new teaser on their Facebook page for "The new F" or the "The future, ahead of schedule" coming on October 30th, 2012. The speculations are for a new F-class Super 35mm cinema camera (F5?) that will probably support 4k and will cost around $20k. In Sony's cinema cameras product line, the F5 will probably be placed above the current PMW-F3L Super 35mm XDCAM EX Full-HD compact camcorder.
