So I was rewatching the trailers of 2.8 and realized that during the announcement trailer (1st trailer), one of the foretellers (Vulpes) is saying: "The Master of Masters has an eye that gazes into the future."
I believe that's why each foreteller keyblade (and the keyblades of Vanitas and Riku) all have a blue eye on their keyblade.
