It's a huge rate, that's for sure. I'm sure it's due to the reasons you mentioned- these ads will remain viable for some time. The actual rate paid out is likely not sustainable, though. Same thing happened to AdSense when it launched- those who got into the private beta in April/May/June were doing gangbusters until the market settled down after that summer.
