It does sound troublesome if this series only last for two years XD.

I think the really tricky part would be the possibility that the new series would still use the DCD Stars system as its arcade game, which means we could see new characters wear old brand coords or perform with Stars characters in DCD even though the story had been changed. Otherwise the new wikia would just introduce anything about the new series and ignore the sharing parts.
