Don't count your chickens yet. Google only has to operate the network for 2 years. And they have not stated if thats from the date of the first customer on or the date when the network is complete.
The network is complete once you turn on the first customer, so that is the same thing. If it's ready to reach the Internet and a customer is on it, it is complete.
If you go with some other definition, the network would never be complete, as you could be adding customers at any time.
