I think I may be alone here, but I personally had no problem with the portrayal of Vergil. I had no qualms with his voice either; I think he is meant to sound more sophisticated and put-together than Dante is and to me, they achieved this. People are comparing this Vergil to the original Vergil, and I get it, it's inevitable, but also you have to remember this is a reboot, a re-imagining of the characters. The creators are allowed to portray them in whichever way possible. Vergil always had his stuff together and was always more calm and collected than Dante, and it seems that aspect of his personality is still intact.
As far as Vergil's arc, I believe he is working with Mundus the entire time. Perhaps due to corruption by Mundus himself, or by his own accord. Perhaps he is using Dante to defeat Mundus and is planning to usurp Mundus' power. Then again the arc could be Vergil's fall from grace. Either way, I'm optimistic for the game and I'm glad Ninja Theory have the testicular fortitude to try something different.
