I guess fans aren't quite sold on the idea. They're reassuring us that TA get priority on both rounds of first-come-first-served. I don't think that was ever in question.
The thing that bothers me is that they make no mention of any price range. Give us a ballpark number. Like chris85 said, I feel that system has the potential to screw early buyers. Not that I think front-stage tickets will go for 50000 yen, but the potential to lose out is there.
