There have been articles stating that it is indeed coming west in the form of digital for PS4 and PS Vita. There is an online petition somewhere and social media campaigning to get the game a physical release.
Only way for Project Setsuna to come to the West as a Vita physical release is if there is enough interest/demand to it.
Publisher's really have become progressively more and more clueless as to what their established consumer base wants and expects from them. Japan and Asia got FFX/X-2 HD Remastered on cartridges, but SquEnix was to cheap to release X-2 on cartridge for the rest of the world opting for a DLC code. And for a variety of reasons X-2 didn't go over well in the rest of the world; A. because it is a rather massive download, B. Because of internet limitations in various areas and regions that make downloading massive files quite a chore, C. Because Vita's proprietary memory cards come at a premium price for storage space, and D. Because most people who buy physical games are quite irked by the audacity of a company at having blatant double standards for the handling of a release across global market regions, in this case physical English language copies in SouthEast Asia, but not for the rest of the English speaking world.
And here, once again, we have SquEnix, known and respected really just for their RPGs outside of Japan, somehow establishing that there would be little to no demand for a traditional-stlye Square RPG outside of Japan... And I might add this is at least the second RPG they will have released for the Vita that has not gotten an English release.
It does make me heavily question what they are thinking when they will bring over some rather forgettable non-RPG title like
Army Corps of Hell to the "western world", and yet deprive us of the quality RPG's that they established themselves with in the western world. It seems if there were actually executives at SquEnix attuned to their global market they would focus more heavily on established gaming genres that have sold well for them since the beginning and that their fanbase would appreciate. I even dare to go so far as to say that Square, and Enix for that matter, RPG exclusives are what really helped to carry the SNES sales and set it apart from the Genesis/Mega Drive in the 90's throughout the "western world". Who doesn't remember that the SNES was nick-named the RPG machine? And this continued on with the PSX and PS2.
Don't get me wrong, I'm still happy that were set to get a physical release of
World of Final Fantasy from SquEnix, but it really does feel like they've turned their backs on the western world market just like Sega has.
