The Olympia brand should not be diluted. The Arnold Classic is now dispersed, but I suspect most who follow the game still consider the Columbus winner 'THE' winner based on the purse and prestige.
Too often in the past in the AAU, NABBA and IFBB, someone who wins a class in a contest declares himself 'the' winner. Some have called themselves Mr. America, when in fact they won one of the divisions, but not the overall. So, hopefully those who win an Arnold will fully describe which Arnold they won. Likewise the Olympia.
