I think Sony calculated that there's more money to be made in the sub 10K market, than selling a limited number of units in the higher end. I doubt we'll see an F5 replacement at IBC. I wonder why Sony, with its sensor making prowess, doesn't just clobber RED or ARRI. I believe (just hearsay) that the same sensor company makes the chips in both RED and ARRI cameras - just to different specs.
