I dont know about you, but a quick cash grab would be fine imo. XV will be loved by the fans unlike XIII, people will want more, XV was a costly project which might not make its money back in the first run. XV-2 would come shortly after being only half the length (~20-25 hours), reusing assets, combat system etc. With a more varied cast, (I'd love an all female cast).
