They haven't announced any plans on extending todays updates yet.. Good sign indeed! Think we'll all be playing 2.3 on time today, or should I instead download a movie and watch it to kill time?

Maintenance has been extended to 1:00 PM PST, approximately two hours past our previous estimate.

We're hoping to not need the full extra two hours, but the amount of changes required for patch 2.3 (which is no slouch in size) are just taking a little bit longer to implement and configure than we previously though would be required.
