Well living in the Arctics I guess I do know a little about shooting in extremely cold weather.
Generally my winter shooting involves shooting in as low as -46C (last years max) and easily in the-20C range of temperatures (aurora hunting at night).
I have never once had the K10D die on me, neither has the K100D so I assume your DL will do just fine too.
Now five major things to remember.
1. batteries
Keep spare batteries warm, they will drain very fast in cold weather.
this goes for AAs in particular.
2. condensation
as with all other large temperature shifts. have a large ziplock bag ready for when you are getting back inside, but the bag in it and let it heat slowly. my K10D took roughly 8 hours to slowly defrost from a couple of hours in below -40C
3. gloves
a pair of surgeon lates glowes under a thinner pair of windtight glowes gets you a long way.
and makes the K10D handable.
4. Lunch
If you step in for say a short break, then remember to leave your gear outside.
5. dress very warm
Being outside taking photos means that you will sit still a lot, this makes it a lot colder on yourself, so dress warmer than you would for just a walk.
most importantly... have fun with it and show us the photos
Hope it was of some help.
