Its been stated before mate,
CAPCOM wouldnt let them have old Dante. It was either "New Dante", or no Dante at all. Also, We wont e getting "Old Dante" until DmC comes out and they release the DLC for the costume for THAT game. (Yes, they will b doing that. i guess they want to save the hype for "Old Dante" for until they release it for their own game).
And yes, i put quotations, because they are both Dante, people need to get the **bleep** over it. he looks real now instead of some weebo fan girls wet dream.
