Yesterday Toyble has released an unfinished version of Dragon Ball AF volume 4 at Comiket in Japan. Because the volume is incomplete, he also included the "final chapter" special as an extra. This "final chapter" was something Toyble originally included in volume 2, back when he had similar deadline problems. Of course you can already read scanlations of this final chapter here. When more scans are available, we will certainly let you know.
