Guys, he's not a monk. He is obviously Arabian/Middle Eastern, he's not Asian in slightest.
I honestly believe he is going to have a skill set based on sand, one skillset based on fire & brimstone spells, and a summon skill set (Think Djinni's, scarabs, scorpions, vipers). It only makes sense because they are releasing the desert act.
He will be a mid range to short range fighter/caster (emphasis on fighter) to fill in one of the gaps in play that are left. WD is a middle to long range caster/fighter (emphasis on caster), Wizard is a long range caster, and Barb is a short range fighter. Which leaves the mid to long range fighter as a ranger/thrown weapon class.
