I'm thrilled beyond belief that we're about to get new resolution options in addition to 120fps at 1k. RED is being rather cryptic, on all fronts, about what the update will feature exactly, but I will say that any of the following will be awesome: 4k 48fps, 4k hdrx 24fps, 5k 24fps. I think we all want 5k @ 24fps, especially those of us coming into the RED world from a 5D Mark II, where our 17mm lens is super wide. Also, 5k is closer to 4k resolution when debayered, though I didn't want to get to technical in this post.
Any other predictions or wants?
