EverQuest II's next expansion, Tears of Veeshan, has been moved to mid-November, according to a letter by Senior Producer Holly Longdale. Calling the expansion "something special," she said that the team will begin the beta on October 15th and that the project is coming together well.
In the letter, she also announced that heroic characters are now scheduled for the first week of October. Longdale said that the team is still "fine-tuning" details for the heroic character release and is making adjustments to Destiny of Velious zones so F2P players have a place for heroic characters to romp.
Finally, if you haven't purchased the Age of Discovery expansion, you might be interested to hear that SOE is selling features from that expansion individually.
