So in summary:
- Vergil is Itsuno's favorite character.
- His favorite weapon is Nevan.
- His favorite style is Swordmaster.
- Asked what weapons we would like to see. Motorcycle, chainsaw, spear, whip, dual swords, other sword types, DRILL SPEAR BABY YEAH, MonHun-type hammer, gun lance, Samurai Edge, baseball bat, Mega Man arm cannon and pool cue got noticed.
- Lady's motorcycle was initially intended as a weapon in DMC3, which would function as a nunchucks-type weapon. They ended up dropping the idea because the motorcycle would clip through the floor. An awesome bit of DMC3 trivia.
- Being asked what he wants / would like to see for future games: Doesn't want any specific features, but wants DMC to be successful, despite it being a difficult game.
- Table Hopper is exclusive to Nero because he wanted Nero to have unique abilities exclusive to him.
- His favorite pizza topping is cheese with honey.
- Sparda rebelled against Mundus because he had fallen in love with Eva, apparently... Eva is an ageless witch confirmed?
- They have considered a versus / PvP feature in the past when looking at the Vergil fights in 3 and Dante fights in 4. Character balance is a concern, especially regarding characters like Lady.
- Itsuno had no input on Dante or Vergil's implementation in MvC3 other than approving their appearances.
Anything else? It's late, so my mind is a bit slow atm.
