It has HDMI out, which means you could pair it with a Blackmagic Intensity card ($250) to capture 4:2:2 uncompressed 24p for less than the price of a decent boom mic setup.
The CMOS chip is true 1920x1080.
We'll have to see how fussy the manual controls are, but this camera just may have DV Rebels everywhere contemplating an impulse buy.
