:lol: I certainly want it, what I do love though is that no one has noticed that the bit of information the OP was referring to has now been taken down as there was no evidence to support the claim.
Yeah, I think it's pretty certain Vergil will grace the next game, I'd love a side story for him, just so we can get the chance to play as him once more. (Without me having to dig out my PS2 and get a new copy of DMC3:SE >_<)
Zato, I refer you to the term Anti-Hero, many games feature the Anti-Hero, like your example, Vegeta, a large party of the story and a primary character, many games have also featured a main character who has less than honourable intentions, so there's no reason Vergil couldn't step in as a main character for a game, hey, they booted out Dante as the main character for 4, so why not bring in Vergil as the main for 5?
I say it once, I'll say it again, Capcom would be shooting themselves in the foot and literally killing themselves if they never brought back Vergil, his fanbase is huge, a huge amount of the DMC fanbase want him back, there's no doubt he'll make a return, but I still take everything Wikipedia says with mountainous piles of salt
