Some sources indicates that Tekken 6 might show up on PSP or PspGo !
My hunch is , It might come out Bundled with PspGo , since the system doesn't have any games availible (even the psp) . Also , SoulCalibur is going to be released on psp too, that shows a trend on Namco-Bandai to publish games like "Tekken5 :DR" on ps3 and psp. Furthermore , PSP HAS NOTHING HERE!
I think it may pass True , to me. Like the MGS ON XBOX360 .
