It seems that German magazine PC Gamer has already been released and includes the last two classes. Considering that the classes coincide with the rumors that have been flying the last week or so (apparently they were revealed to the press at the same time as the Imperial Agent and some people claimed to have been at the press event) and how authentic the scans look it's likely true.
According to the articles (and other rumors) the last two classes are: Jedi Consular and Sith Inquisitor.
Yes, that means another Jedi and Sith class, which makes absolutely no sense (and means that there's no class based on Leia/Padmé either). Deeply, deeply disappointing and I must say that my anticipation for this game, my desire to play it, has dropped well below zero.
Have fun reading the tragedy from the scans (if you read German) while I consider whether I want to continue with this blog or not (after this is made official).
[UPDATE] Rumor is not a rumor anymore. <sigh>
