After playing DMC4 it would make sense not to bring Vergil back into the story to get back yamato from Nero(not that i have anything agaisnt Nero) but as Nero is some how a decendant of Sparda it would be good to see Nero get a full devil trigger by Vergil stabbing Nero with the yamato,
It would also be nice to have Dante, Vergil and Nero all have separate disc's s they have about 15 to 20 missions each in the next game,
At the end of DMC3 when Dante is able to defeat Vergil, he cannot convince him to return to the Human World, and Vergil falls even deeper into the Netherworld.
In the epilogue, Vergil is seen in the Room of Fallen Ones, while three glowing orbs approach. Vergil recognizes the approaching devil, and prepares to defeat him, remarking "If my father could do it, I should be able to do it too." However, in his weakened state he is defeated and corrupted into becoming Nelo Angelo
So if Virgil is a villian why did he try to defeat Mundas, i think he was just trying to gain more power so he could protect the people he cares about,
What do other people think?
