I would try to strike a balance of listening to the fans and still keep with designing a game properly. I would make a game DMC game called, "Devil May Cry: Origins." It would feature Sparda and Eva's story. And then, I would make DMC 3 again, but this time, I would add even more length to the game by adding the chapters from the manga in the game. Also, I would make Vergil's game path different from Dante's game path. While I loved Vergil's game play and mechanics in DMC 3, I was a little disappointed that I was going through the same levels as Dante. I would remake that.
Anyway, that's what I would do.
Newer isn't always better. And I shall keep Dante's Force Edge polished and sharp till he comes back.
