Sequel to Battle of Gods?
According to a few of the wiki pages on here, at the end of Battle of Gods, Whis is supposed to karate chop Bills on the neck, knocking him out. He then goes on to say that Bills will wake up again in 3 years time.
Now since Pan is not yet born during the movie and given that she is at least 3 or 4 years old at the end of DBZ this means that Bills will wake up before the end of DBZ. Does anyone think that the door has been left open for a sequel in which Bills returns?
