Honestly, no one cared about it until today. There were posts regarding EGA, but never like this.
But as I've said in other threads, what was Bioware's other decision? Go back on their word and let everyone in at once, regardless of pre-order date? Then you'd have page after page after page of people who pre-ordered day one screaming that Bioware lied to them and being upset that Bioware took away their reward for being first in line to pre-order.
Personally, I think they were damned if they do, damned if the don't. This way, though, they at least keep to their word. Once Bioware made the decision (and stuck with said decision) to have a staggered early access, it was on the customers to decide whether or not they wanted to go ahead and pre-order or not.
