Well, he must have always had white hair otherwise, some of the order members would have inquired about his unusual new hair-colour.
I don't believe he is Sparda's son, as he clearly isn't a half demon and his demonic powers are way weaker compaired to Dante. Even Sanctus said they would prefer to use Dante as a battery to the saviour as he had more of Sparda into him, but they took what they got.
Being a son of Vergil would actually be nice - but not if Vergil just visited a prostitute. If there was a story behind that, it would be nice to know of it. Even the novel made this weird by mentioning a prostitute.
Before the game was available I thought Nero was some sort of experiment, being infused with Sparda's blood from a young age, to adapt and slowly evolve into what he is now. Since Agnus and the rest had no idea he was a demon before the incident with the Yamato though, that theory died.
In the end we know nothing. *sigh*
