I spoke with someone close to Christian today and was told he just recently got the walking boot taken off his ankle. I'm told he still has to wear it every other day and is still in a lot of pain. The feeling is he would have been better off breaking his ankle given the severity of the sprain. The injury occurred on November 9th at a Smackdown house show in Belgium.
Due to increased speculation about Christian being part of the cryptic videos on Raw Supershow, I asked if he was a possibility. My source said that was "very doubtful" because he can still "barely walk."
While WWE plans for him to be back early next year, it certainly appears his return to the ring is not imminent.
To answer the multitude of questions, I have only heard two names for the cryptic videos since they began airing - Chris Jericho and The Undertaker. However, I am unable to confirm any return at this point.
