Western devs simply have better alternatives, so without special incentive, they develop for the alternative like PS4/Xbone or smartphones when they have a way bigger chance to make more profit out of.
That's the main reason imo why Vita, Wii U and 3DS have shitty support from Western 3rd parties. 3DS has the install base but it seems to consist of typical Nintendo fans who don't buy pretty much anything other than Nintendo evergreens and some exclusives. I mean FIFA on Vita outsold its 3DS counterpart consistently, same with the recent Batman game iirc, it definitely was close, when the size of the userbase is not.
As for Japan, big developers from there have been making some questionable decisions for quite some time anyway. Majority is on the smartphone bandwagon and you can't deny the userbase difference there, which shows itself on the big hitters, Mon Hun 4 wouldn't have sold as well on the Vita as the 3DS (a port wouldn't hurt though). So I understand that they are not doing exclusive content for the platform without incentive.
Some of their porting decisions though? Fucking delusional. People are crying for some games that could only be localised and put digitally on the Store and would more than recuperate the cost.
So it is happening...PS4 preorder.
Greatness Awaits!
