XSEED is the most inconsistent publisher out of the niche ones. The other time it was this dire was during the beginning of the Vita's life, where everything, be it for the Vita or other platforms, were all DD-only. Now they're all PC ports. I think they've just lost one too many partnerships and have to fret for work, which is why one would think they'd go back to Marvelous' backlog and localize some Vita titles while they still can.
It's weird how the localization houses can go in cycles. At least at the start of Vita's life, XSEED were releasing games - NISA and had like nothing for the first couple of years of Vita's life and look at them now, probably the biggest Vita publisher in 2017.
XSEED really fell off though. I kinda think something must've happened with the management there, because it really feels like a seismic shift in priorities. They used to mix in bread & butter franchises with vanity projects in between; now it seems like bread & butter franchises with "EVERYTHING MUST BE ON PC" attitude.
I suppose they did take a gamble on Touhou (which backfired for them - shocking!), but we're worlds apart from the company they used to be. I wish Tom was still around to engage on GAF. I'll have to sign up to their new forums so I can speak to him again.
I'll still never really get over what they did with skipping every single one of those Vita exclusives, though. I mean, I get miffed about NISA skipping a number of their ones, but at least they got round to quite a few in the end. XSEED just ditched EVERYTHING from 2015 onwards and chased after things like Fate/Extella and Akiba's Beat which got delayed and delayed and delayed leaving them with not much other than precious PC porting throughout the year.
