Haha glad I'm not the only one who noticed this.
I feel bad for Blizz tbh. Firelands will be released no later than Ulduar was in WotLK, yet because it was hinted that 4.1 would be Firelands it has caused a major uprising of bitching. They should have just said FU to the players and released ZA/ZG with Firelands in May. It would have caused less complaining, even though the players were getting less content. The community is so funny sometimes.
