Will there be 7* characters in the future?
New levels come out and each time their complexity grows and soon even 6* characters at rank 5 will not be able to cope with them. I think that 7* characters will still come out, because the game has room to grow. There is no end to this game, so I think it will be good to continue to develop it, adding to it: new levels, new catalysts and new * characters.
