Capcom-Unity has the latest installment from the Tatsunoko vs. Capcom developer's blog, with the game's producer fielding questions from the fans."Cross Generation of Heroes" (CGOH) was released at the arcade and then on the Wii and we received some good feedback. Therefore there was a discussion in Capcom about whether we can release it in the pan-western territories.
But, once I got this started, the complexity of the franshises in the pan-western territories, amount of time it takes to work on each of them, money, people, other projects, etc. There was a time when the project was about to be put on hold.
(to say the truth, the revenue of the game wasn't really the problem)
