Shot the HVX up at the Iditarod in Alaska; Bernie and Mike Caporale took it the whole 1100 miles, shooting in 67 degrees below zero. No problems other than the LCD freezing.
Heat seems to be more of a problem than cold.
The 7D, I'd be less worried about it in cold, because a) it runs hot anyway, so cold can only help, and b) it's pretty well sealed, so it should be able to keep itself warm.
But, that's just supposition; obviously it hasn't even been out long enough for it to get really cold in the northern hemisphere yet.

Dear dude with a weird name I can't even copy without getting a migraine,
Yes.
Kind regards,

PS: LCDs will give you problems well before you hit a cold bug on a CPU. They have liquid in them, so yea... no fun if you can't use the screen. Solarization is a common side effect, or so I hear. I guess you could still shoot without a screen if you used the OVF, but don't tear or you might have a 7D stuck to your eye lid.
Yes.

Ah yes, that makes sense. A solution might be to connect an external monitor that you could indepedently heat...
Er, but you can't use the OVF while recording video. I see that the migraine has already begun to affect your memory!I guess you could still shoot without a screen if you used the OVF, but don't tear or you might have a 7D stuck to your eye lid.
Hehe... oh, yea, true. No migraine here, just brain dead from being sick and overworked.
With external monitors you can slap a chemical hand warmer and you should be fine. The main deal would be to prevent the back cover from getting super cold and robbing all of the heat off the LCD panel itself. I heard people used USB powered coffee cup warmers for the RED EVF, powered right off the camera (might be firewire). Also heard about people bagging up the camera which helps trap some of it's heat.
The big issue is condensation though. Bringing lenses from cold to warm. A lens might fog up so much that you might get condensation inside... and THAT is a killer issue. The trick being to try to acclimate them slowly, and an other good idea being to put them in a bag with one or two silica blocks like the ones from Pelican which are reusable. You just pop them in the oven for three hours, at 350 I think, and they are good to go again... that could help keep the lodging toasty at night.
Also be careful in extreme low temps with your lenses. I heard New In Town brought lenses out straight from indoors to something like -30 farenheit when the wind was blowing a bit and CRACK... they went through several lenses needing to replace all of the front elements! ouch...
