Hello again =]
I don't think they're ever going to release an English Gundam game outside of Japan unless it's published by Namco Bandai and they give the word on it. The only notable ones are the Gundam Musou games. They are good, but they still feel like Dynasty Warriors, not that I have a problem with it.
Good ones like the Gundam VS games are the ones you'll never find outside Japan and those are by far the best Gundam games as they simulate actual Gundam battles. Gundam Extremem VS is the most latest Gundam game in Japan, how I'd love to get my hands on it if it's ever released in the west. =]
