Shooting at 14fps. The new Canon 1DX launched just today. RRP to be announced.
Excuse the video quality. It's taken off the iPhone 3GS, uploaded via the Flickr app.
Canon wouldn't allow us to take home any pictures. But from what I see, the ISO performance surpasses that of the 5D2 and their predecessors a fair bit. That's your two stops of wonder working for you.
