I like that fans so freely criticize her acting and then you see those threads with dream casting choices and basically any Maxim model is contender for the role of Emma on the basis of being blonde and pretty. Just like any redhead ever is at some point in time considered for Jean Grey.
People should just relax, it was a small role with not much material anyways. I'd love to see them bring Emma back and do something interesting with her, January Jones could pull it together for this one anyways.
PLUS, the last movie ended with her being recruited by Magneto...are they just going to ignore it?
