Quote from Daniel Erickson
The species/class combo list you're referencing is not accurate. If it does appear in the magazine, that's unfortunate.
My guess is that an enthusiastic member of the press wrote down everything he saw in the character creation screen which, as we've stated often, is nowhere near final. Occasionally we'll have species in odd classes or in all classes because of a bug or testing.
Hope that helps!
As with any game in development, everything in any current or past build is subject to change. It is important to note that no species/class combination is final until BioWare announces it. Thanks to Gerbo and Meglivorn for pointing out Daniel Erickson's comment in the Dev Tracker.
