We have tested both Asura's Wrath - 360 (Region Free) (In stock usually ships within 24hrs) and Blazblue: Continuum Shift EXTEND - 360 (Preorder) on our PAL XBOX 360 console and can confirm that Asura's Wrath IS region free but unfortunately Blazblue: Continuum shift extend is not.
Look for more PAL region free tests soon!
