Devil May Cry is a great franchise and I'll assume – just for the sake of being optimistic – that Resident Evil 6 is on the way…sans the old-fashioned tank controls. For the record, I didn't mind RE5 (had some fun with it) but certain mechanics just don't age very well.
However, I still miss the Onimusha series. The original title was one of the first great games on the PS2, and that sparked an awesome series that continued to satisfy my action craving for years. Oddly enough, it utilized a similar control scheme to Resident Evil ; you know, you have to turn in a particular direction first and then move? But for some reason, it didn't pose much of a problem for me and besides, didn't they get rid of that old control format at some point? I believe I remember playing one of the later titles and going, "oooooh, they changed it." But I might be thinking about something else.
Japanese developers are having a hard time making games for the Western crowd but if I remember correctly, the Onimusha titles sold very well here, which is part of the reason we received so many installments. Action is action, even if there's a significant Japanese tone to it and besides, how many other action games feature a samurai? And don't mention Dynasty Warriors ; that's a completely different form of gameplay. I actually think Capcom accumulated enough franchise fans to risk a new title for current consoles, because every time these games are mentioned, the majority of people are going: "hell yeah, I'd buy a new Onimusha !"
At any rate, I hope Capcom doesn't leave one of its more popular franchises in the past forever. And by the way, I still maintain that Onimusha 3 had one of the best introduction CG sequences in the history of gaming, perhaps second only to Final Fantasy VIII .
