Anyone else wonder what they did with Voldemort's body after the battle?

They took Voldemort's body and laid it in a chamber off the Hall, away from the bodies of Fred, Tonks, Lupin, Collin Creevey, and fifty others who had died fighting him. -Deathly Hallows, Ch. 36 "The Flaw in the Plan"

So like, do you think they just cremated him, and scattered the ashes in some middle-of-nowhere bog? Maybe some... vengeful individuals cut pieces off as keepsakes? Is it being studied in the Dept. of Mysteries?

Let's hear your theories!
