So Trish is using Pandora...does that mean that Dante will have his own Devil Arms and the ones we saw before, were supposed to have been used by other characters such as Lady having to access some of Pandoras techniques? I mean they're mostly Gun related so who knows, and by the looks of it Dante and Vergil meet at the be beginning and it is only halfway through the game that Nero comes into play, which is why we see Nero face Dante at the supposed beginning of the game in Vanila. I think That Vergil will meet up with Dante and they will lock swords from time to time and eventually Vergils sword will be stolen and I think the order are the ones who entrap him, and use his power to poer the Angelos. And Nero frees him which is why he's carrying his sword only to return it back to Vergil in the end... I know it's just a theory but it can work really well if you think outside the box.
