Gill isn't on the leaked list, Gail is (unless it's a typo/mistranslation). Gill isn't in the DLC polls Top 10 either, but Vergil is. I only brought him up because God's Beard brought it up. I don't care about him either and it seems not many people either. Would rather have M.Bison in if we were to pick a SF character, hell even Juri.
And I was kidding about the Vergil resurrection thing. If Vergil is in the game, then he would be like a Strider-type character because that's in essence his character/play style. Teleports, projectiles, sword slashes, orbital swords hovering around him to keep opponents pinned down and a "trigger" where he basically turns into Nelo Angelo (sort of like DT with Dante but different). He would be top tier for sure though, if he gets the same treatment as Dante.
I don't think the whole "DMC already has 2 characters" is really valid. SF has 4, Darkstalkers has 3, RE has 3 and Megaman most likely will have 3 also.
I am with God's Beard, I want interesting play styles. If they happen to incorporate fan favorites as well then that's great too. Vergil has an interesting play style, and if Strider has legal issues then Vergil is the next best thing.
