It seems like this game is being made by Ganbarion (who made the Grand Battle series and Jump Superstars… more on that in a sec.) which makes me wonder...
For the new U.S. Grand Battle (Grand Adventure) if Ganbarion is working on Unlimited Adventure, does that mean Namco Bandai USA is working on Grand Adventure all alone? And if what Battle Franky says is true about a Jump Superstars sequel, does that mean Ganbarion isn't working on it, or are their development teams large enough to handle all three projects?
