why would you not just order the digital copy?
I had it DL'ed completely like 2 weeks ago, fully installed at 8am like 18 hours before servers went live.
They had alot of downtime yesterday, and servers were extremely busy for the first 4 hours of opening night.
I've still had PLENTY of time to play, plus Blizz has gotten REALLY good at this kind of stuff. Very soon downtime will be to regular maintenance only, they know what is expected. They've been doing multiplayer games (not single player games put on the internet) for like 20 years.
Nothing is out of the ordinary for Blizzard on this one.
*pretty sure you can still go dL the whole game client and then just authenticate it when your key gets here.
