Lady has the Kalina Anne grapple and Trish technically has flight. They could work those into the traversal somehow.
Maybe she'll use her firearms/grenades to melee, like gun-fu.
I'm actually hoping they're doing the right thing and restructuring the parts of levels that rely on the Devil Bringer so you can also play as Nero in any level and play as Dante in any level.
I'm a bit bummed that this seems to confirm that there won't, in fact, be a new Vergil campaign, though. But I always thought that'd be the case because of what's scalable to develop and what isn't (new level assets might be more costly to include).
SUPER excited to see how Lady and Trish play, especially Lady (I wanna see Trish play like she does in MvC3 with a heavy reliance on the Sparda's ability to change shape). And yeah, Lady using firearms for melee attacks could result in a great sly Bayonetta tribute character. I hope she has a double jump that causes damage to enemies (by rocket jumping).
I'm definitely hoping this also includes stuff like a classic weapons pack for Dante (Cerberus, A&R, Nevan, Artemis at least, please) and (if we're REALLY REALLY lucky) classic bosses so we can re-fight Phantom, Cerberus, Beowulf, even classic Vergil and Nelo Angelo.
