"it can now shoot 24,25 or 30fps as well as at higher frames at a reduced frame size"
Why would you want to shoot higher than 30fps?
My Canon DSLR can shoot video at 60fps, but I haven't figured out a purpose to that, other than eating up memory faster.
Also, I can't see the point to reducing the frame size (below the maximum) unless I was running low on memory. If I ultimately want to have a reduced frame size, then I can convert that in post-processing. But if I shoot at a reduced frame size, it is difficult to convert up to a maximum size without compromises.
