Not sure. They already did the majority of their server stress testing in rounds 1 and 2, but they also had a major delay in rolling out NA keys yesterday so many people who were supposed to get them have not yet.
I have a feeling they'll be playing catch up on beta keys over the weekend, and then they may send some more out for next weekend.

I can't understand anyone who skips the cutscenes of a Final Fantasy game. That's like going to Texas and not getting barbecue.
