Ok, so, I Theorize 2 options. the first one with the RSnail team in New Horizons, you know, with all the stuff, parties and mini games before 2008. I don't think that CP would become that big, maybe It would still online but making it better such as other online MMO's.
And, the other one by the hand of Sony. Maybe developing other spin-offs in their actual consoles, and even a motion picture or fully animated cartoon, who knows? Sony makes a lot of stuff since early 2000's, and Club Penguin was fresh and New, so, It could be really interesting to have some "takeover parties" like, Spider-Man takeover? maybe? I don't Know haha.
