Saw this story on Darth Hater, where they where talking about the frontpage of the german magazine “PC Games“. What it sais is, that BioWare is going to reveal the last two classes in the next issue of the magazine.
The interesting part is, the magazine is on sale from wednesday 25th. so it might not be long untill we know more about the last two classes.

PC Games also had the opportunity to test the game, so might be worth buying it for all the german fans.
