Not sure yet, but what I do know is that Vergil wasn't in DMC4 (hardly even mentioned) but it's clear he's relevant to the story in some way, so either Crapcum is going the DMC3 route where you're basically just using a Vergil skin but playing Dante's missions - in this case it would be Nero/Dante's missions - or they're actually giving him a unique story and missions. If it's the latter, it can be taken as a sign that maybe the original series will be continued, but Crapcum is pretty stupid so I'll remain skeptical until some more info is released.
