Well, Suda says that the scenario is almost 100% done already as well as the game system, too. He first thought of making it on PS2, but Wada (Marvelous Interactive) insisted on making it on Wii. Suda, back then, didn't know about the Wii's controller. Now he is more than convinced that the game is for Wii. So, now he says the game for "tuning". He also precises "Beam Katana" instead of calling it a "Beam Saber". And so, like I said earlier, the hero of the game, Travis is a big fan of a fictitious anime "Magical Girl 'Bizarre Jilly'".
....what else? Ah yep. Suda wants it to be releaset around the "warm" period of the year 2007, but then he goes "Maybe it will be out already around this time next year (TGS), but... maybe NOT!"....so, we can't know really about the release date! He does seem wanting to release it sooner, though!
Hope this could help knowing a liiiiitttle bit about the game!
