I just wanted to clear something with you all... Since there is nothing mentioned in the end of books as to the whereabouts of the Invisibility Cloak and the Marauder's Map, I'm thinking Harry still had possession and passed it on to his eldest son, James Sirius.
But since there really is no hard evidence of this, if anyone wants to fight for claims, or vote to rule them out of our play completely, I'm definitely up for a group debate on the topic.
