The theory is that Capcom want those IPs to die either because they think no one is interested anymore or the creators of those IPs left Capcom on unfriendly terms.
Like Megaman is probably one of their most popular franchises along side Street Fighter but for some reason they are content to just let the IP die for some reason and only bring out a collection every now and then to shut the fans up.
It's seems clear to ma that Capcom wants these IP's to die and don't like that the fans won't let them die.
