Accent Core 2.1 coming to PS2s next year?

Lucky US gamers evaded the buggy PS2 version of Guilty Gear XX: Accent Core Arc System Works hastily released in Japan. Aksys released an updated version, Japanese gamers got an apology. Perhaps they are going to make it up to their fans with a revised version of Guilty Gear XX: Accent Core. Play-Asia has a listing up for Guilty Gear XX Accent Core Plus, which is being sold as a full price game. Since Arc System Works seems to be selling this they must have more features than bug fixes. I can’t imagine them charging their loyal fans for a broken game and a second time for a properly working build.
