Actually no, unless you're talking about the US and parts of Europe. Most of Europe loves the Tatsunoko characters.
Some confirmed details about the English port:
-Will have new stages
-Hakushon Daimaoh (the genie) has been cut out of the game due to licensing issues. Which is odd considering how big "The Genie Family" (called "Bob in a Bottle" in Italy) was in Europe.
-Capcom may add 5 new characters. But this detail hasn't been confirmed yet.
-They also may add online to the game (the Japanese version didn't have it).
-The onscreen HUD has been redesigned.
-Certain balance issues like Roll being able to repeatedly OTG Daimaoh (i.e. hit him repeatedly when he's laying down) have been fixed or are in the process of being fixed.
Also, about Namco x Capcom, its omission from overseas release was because Namco was scared that a lot of the characters would be too obscure for any audience that wasn't Japanese. So Namco canned the translation of the game. Completely different from this situation. Capcom tried to get as many licenses as they could and they did. :greenie:
