I don't think so, i mean localization companies made some good money with vita localizations, people are still here and many other japanese vita games are in development, i don't see the reason to waste the opportunity.
I'm disappointed by XSeed, the only localization annnounced was Xanadu Next for pc, making ports is good and all but since localization companies are few and the demand of localizations is high(that's why i always say that there are few localization "slots" that should be used for the very best games) i would have stayed focused on that front.
If really there's a shift then it's not from vita localizations to other platform localizations, but from localizations to ports imo.
what localizations would you like to see? keep in mind that anything sega (excluding atlus) is a complete nonstarter. i'm genuinely interested because i really don't think there's a ton out there with strong appeal to the niche market.
