The Loge's were always expected to go first as they are catering to the 30 something grads who have enough money for club seats, not enough for a suite, but have friends they want to hang with. Perfect fit, not surprised they sold out.
The suites are going OK from what I have heard. That demand is lower than assumed but not by too much, they will get all those done... And they may already and just haven't finished contracts.
The demand for club seats is what has been most surprising to athletics from the folks I've talked too... Lots of people said they were interested but are balking at the relatively higher prices.
