Beyond3D posted the second part of a two part interview with Futuremark.

FutureMark: I personally think HDR is a great thing, and urge every developer out there to go for it! If it’s done right, it can open up many new doors of visual treats for gamers. I have read many discussions about HDR on the net, and there seems to be very mixed opinions of what HDR really is/does. Most users think HDR is simply a new "better" bloom effect than what was possible on SM1.X/2.0 hardware. That’s not entirely wrong, but certainly not the whole truth.
