An interview with director Hajime Tabata included in the Final Fantasy Ultimania Guidebook reveals there are plans for an international release of the title. Personally im not suprised, and most likely we will see this released next year (i hope!).
Square Enix has not released information for a possible US release yet, but given it’s a Final Fantasy game was ilogic not to have an international release of the highly popular franchise.
Hajima Tabata also discussed the possibility for a sequel, and Square already registered domain names for Type-1 to Type-3 so we will see a lot of Final Fantasy goodness coming to our PSP’s.
