Tatsunoko vs Capcom is coming to the West. Hurrah! That's enough cause for celebration, but more corks may need to be popped if the game makes its way over with some online multiplayer.
The Japanese version of the game shipped without it (you could only play against other humans on the same console). Which may cut it in Japan, but in the West, a fighter without online multiplayer just isn't going to cut it.
Which is why Capcom are looking into it. Producer Ryota Niitsuma has told Nintendo Power "We listened to feedback from our fans and marketing/sales teams in other territories in order to implement new features into the game this time around".
While he didn't specifically mention what some of those other features may be, he does strongly suggest the inclusion of online multiplayer, saying "we are still working this out, but stay tuned for more information coming soon".
