It’s been some time since we last heard of Arc System Works’ next installment of Guilty Gear, Guilty Gear Xrd Sign, but as of today the game is available in Japan via Sega’s ALL.NET Pras Multi 2 arcade network (i.e., it can be downloaded direct to ALL.NET+2 units). From the video description, it sounds like the game has undergone a lot of fine tuning since it was seen on some location tests last year. They also have released the opening video to the game to lay out the basic story and characters.

While not impossible, imports on this will be a little more difficult given the online distribution nature of the game but it already has been confirmed for PS3 & PS4 for the consumer side of the game.
