The patch is 53.66mb, although it's always a bit larger than it says.
It's better than most other WoW patches I've DLed on patch days, it started pretty quickly, but that might be because it's 7:30am
Luckily I have school so I have to get up.
My Wireless is running at 18Mbps (so it says when I double click the wireless thing in the system tray but then drops as low as two. It's usually stationary at 1Mbps when I want to play WoW.
I'll test the patch out tonight, any comments on it from those who have already got it?
