I believe they should bring back Nero but I don't believe that they should leave out Dante as much as they did. I love both characters but 4 was mostly about Nero, then agan they do have to start out a character somewhere. I hope in 5 (if it is made) they show more about Nero, he's kind of a mystery character as of right now and I'd like to know what exactly his story is cause some people say he's Vergil's son. I highly doubt that, some say he's Dante's, I severly doubt that even more. I personaly believe he somehow inherited Vergil's power after recieving an injury to his right arm and it was transformed since he "needed power" in order to protect Kyrie. It's been said that he was born with it, and yadda, yadda. I want the 5th game to clearify Nero's story some at least. I also think they should give Dante a little more puropuse other than cleaning up Nero's messes and unfinished battles. Even though I did get some feeling that Dante was there for a little more than that, I think he knew about Nero almost the whole time cause in the first cutscene when Kyrie's singing and Nero's fighting Dante's watching him from the rooftop the entire time, observing in a way...well anyway this is about Nero coming back in the 5th game not the whole entire game plot ^^' sorry for this being so long.
