There was recently an interview with Jay Wilson regarding the Monk and his as-of-yet unrevealed skills, as well as some other paradoxes that might not have been anticipated.
Official Blizzard Quote:
Most of the Monks skills will focus on combat skills and attacks, along with his various escape skills. And we talked at Blizzcon that we`re likely to put some defensive and supportive abilities on him. Possibly Auras. We`ve not done the next round of skills on him yet so we`re not exactly sure.
