Because the former (if the latest Corocoro is anything to go by) seems to be going for Digimon-level of edgyness for the next YW proyect, and considering Pokemon copied the whole magic watch/bracelet and ghost companion thing for SUMO, I wouldn't be surprised if they did the same for the 8th gen.

think about it, come back, apologize, then kill yourself
ghosts arent edgy stop being stupid
