yeah me too i was thinking about the same question about why did dumbledore keep the cloak coz he is the most powerful wizard in the world (even voldemort fears him) that can be invisible without the cloak and also knows how to use difficult spells not even hermione can't do. so i think james told dumbledore that to pass the cloak to harry when he sarts hogwars. and i can't wait for jo to finshed her books but in away i don't want the potter adventure to end but hopefully she would a great title for her 7th book coz she the expert on the magic world well as the muggle world.
