When will there be another undisputed heavyweight as it is normally every 10 years now?

The last time there was an undidputed heavyweight champion the Duke of Normandy (William The Conqueror) defeated King Harold II at the Battle of Hastings in 1066 which is depicted on the Bayeux Tapestry and all that, William commissioned the ancient survey/doent the Domesday Book in 1086 and also commissioned the Tower of London in 1078, Richard I (The Lionheart) fought against Saladin during the Crusades and there was a King's Ransom for Richard in 1194 before he died in 1199 and his brother King John ascended the throne and sealed the great charter the Magna Carta at Runnymede in 1215 lol. Okay I have said all this before but it has been a long time since we had an undisputed champion.
