Marvel Comics released a new teaser for Brian Michael Bendis and Chris Bachalo’s Marvel NOW! title Uncanny X-Men #1, which debuts next month on February 13th.  The new image shows Cyclops, Magik, Magneto, Emma Frost, and what looks like two mutant recruits and warns that "One of These X-Men Is a Traitor."
 
The question for X-Men fans to ponder over the next month is which of the figures in the new poster has gone over to the dark side?  Magneto of course has changed from a white hat to a black hat and then back and forth many times over the decades, which makes him the most likely choice, but Magik in her current incarnation has by her own admission no soul or moral compass.  But then who is betraying whom, and are Cyclops and his band freedom fighters or terrorists?
