My gut feel is the opposite. This is a ridiculous phone, for a ridiculous price. I personally wanted it and couldn't get it Today yet, and I know of at least 5 other people (outside the US) who've been pinging me to see if it's going to be available anytime soon. Pretty sure it's a demand-issue this time.
If the numbers are good, they'll brag about them. If they don't, it's a pretty good sign that it's supply.
Let's say they had a quarter million units for sale for their first run (given their Nex7 sales, totally reasonable). That means they're selling ~80 phones a second.
Now did Apple sell more? Sure. Does that mean these numbers are bad, even in a relative sense given the obscurity of the Nexus brand, the troubles during launch and the location of sale?
No. Supply or Demand, this is good for Nexus.
