Unlikely. Nero has no amulet, uses a very distinct gun, that's Rebellion and, even if his arm doesn't look like a dinosaur's now, there is no Kyrie around to fawn over. There are too many identifiers that it's Dante. Is possible it's Nero? Sure. It'd be a silly twist but not impossible. I just don't see anything Nero besides the voice and hair.So....maybe it's actually Nero, all grown up, taking over Dante's role because he's retired.
