What I like the most about this revelation is that it makes viable the addition of characters from the same series and company when we talk about third party. A new paradigm break in the series. Other interesting paradigm breaks that we have would be:
Alucard show that AT can become fighters;
Sora: showing that the series is open to bring characters from non-game origins if they are only to make a video game character more authentic;
Characters from competing companies, alias Sony and Microsoft, especially Sony. Like, Master Chief and, even more complicated, Kratos. Even so, they would be cases apart;
