Namco-Bandai has another Gundam game in the works: a new entry in their long-forgotten Gaiden line (which spawned the Blue Destiny series in Sega Saturn, the Rise from the Ashes game in the Dreamcast, Zeonic War in the PS2). Basically, a new One-Year-War game with obscure robots that were in other games in the past are featured in this game. Gameplay seems to be 3rd person in teams of 3 robots that you can switch control of. Customization of robots also confirmed. Storyline: either you're a Feddie or a Zeon.
I'll keep my eyes on this but I don't expect any large popularity or following with this game.
