I personally think it will be Annabeth, as her back story and character has been explained. However, I find her boring - she just doesnt have any active powers and you would think the 7 would be amongst the most powerful demigods alive. I do hope though that a child of the Minor Gods like Hecate or Hypnos could be the 7th :)
