Some are saying the serial port at the bottom, which is where the video stream comes from, has a different number of pins to the current model's, and so it won't be possible. Who knows though- I thought the signal would come from the mini-jack and not the serial thingy. Guess we'll have to wait and see. And to avoid any confusion, the pre-production units run 3.60. Also, the icons used for the 'Connected Display' menu are all in firmwares from 3.30 upward.
