This addition shows that a crossover between the two games is certainly possible, but whether it happens or not is something we'll have to wait and see.
The folks over at Team Ninja have just announced that Akira Yuki from 'Virtua Fighter' will be making an appearance in 'Dead or Alive 5.' It's the first time the 'Virtua Fighter' lead has appeared in a console game since 2007. Japanese arcades have been regularly updated with new versions of the game, but the Xbox 360 and PlayStation 3 are still lacking.
A few weeks ago, Team Ninja lead Yokuske Hayashi talked about a potential crossover with 'Virtua Fighter' and it seems that there's a bit more to the suggestion than just a desire. Time will tell if this is simply a one-off appearance or the beginning of something bigger for the fighting game franchise.
