Guilty Gear Xrd was featured on the Denjin Getcha stream a few days ago. Akira and Pachi were there to show off more Sin and Elphelt, and during their matches you can see that there is finally a rematch menu! This is great news, since GG has not had a proper rematch option since the PS2 port of Accent Core. It is ridiculous how such a key feature got taken out in so many ArcSys games. But anyway, the rematch menu asks both players if they want to continue or go back to char select/menu. You can watch the video below.
During the stream a story mode clip featuring Sol, Ky, Leo, Ramlethal, and Elphelt was shown. Apparently, it is somewhere in the introduction of the story. The clip has been uploaded on the official Arc System Works Youtube account, and you can watch it below.
Finally, the 4gamer GGXrd wiki has gotten a minor update. There are now images of all four taunts and all six palettes for every character.
