The last press release from Namco Bandai said Soulcalibur: Broken Destiny will bring the search for the cursed sword to PSPs this summer. By “summer” Namco Bandai really meant August 27… for Japan.
That’s what the Japanese Soucalibur: Broken Destiny page says. Since Project Soul will be done adapting Soulcalibur IV for the PSP then, a domestic release shouldn’t be far behind.
Soulcalibur: Broken Destiny uses the armor crushing system from Soulcalibur IV and adds new characters to the roster like Dampierre and Kratos from God of War
