Other classes

What other classes to be featured in Diablo III besides the Barbarian and Witch Doctor is unknown at this time. More information will surely come at BlizzCon 2008.

Known Information

We have heard several statements saying that the Barbarian will be the only recurring character class from Diablo II, but that there might be a possibility for one or so class to come in an eventual expansion to Diablo III. We also know that the Diablo III dev team at once though about making a Dervish class, but no information if that idea is completely shelved. It seems highly unlikely that the Dervish would appear though, as Blizzard have avoided talking about upcoming classes.

Speculation

Blizzard replied to questions as to why the Necromancer was not included in the line-up, saying it's so similar to the Witch Doctor. Jay Wilson responded that the Witch Doctor shall be made enough different from the Necro that if they decide to bring the Necro in later, their roles will not overlap.
