Odds are, I'd say, that we'll see our first level 80 sometime this afternoon (and probably in Europe, since they got a little bit of a time zone head start) -- we've had reports come in from one very obnoxious Paladin, but his claims to level 80 aren't actually true. But in the meantime, here's the first level 70 Death Knight we've heard of: Arello of Raptors Open Doors on Shattered Hand dinged 70 as a Death Knight in Northrend's New Agamand. The Armory doesn't have his character in yet, but this seems credible to us.

We're not sure he's the absolute first, though, just the first we've heard of -- anyone else have proof of a Death Knight at 70 already? And we'll keep an eye out for (credible) claims of level 80 firsts -- the run from level 60 to 70 took about 28 hours the first time around, so unless Blizzard did things a lot different, we'll probably see it sometime today.
