I'm talking about memory cards not internal memory. Sony took a good design from the PSP era and decided they wanted to have full control over it. So with the Vita it got Sony only memory cards and a bunch of system DRM because remember, PSP was a huge homebrew and fun hack machine. Publishers and studios hated it for that.
The system is otherwise fantastic. It should be a hit but because of Sony's choices with memory, it is only a hit in Japan. But hey, no region locking so they at least got that right. It does get more JRPG ports. However, you won't find them in stores. Lot of them go straight to digital or if they do retail, they aren't sold in a lot of places. Heck not even Gamestop gets some of the more rare titles.
The fact that Unity works on it and Indie devs have been porting titles to Vita, means it is open to Indie devs. Muse has stated they'd look into it if Sony sent them a Vita dev kit. But frankly, even with the Vita's power, I don't think we'd see it happen. If it did, it would have to be a trimmed version of GOIO. Something standalone or like COOP mode might work better. But realistically Sony needs to release a new handheld that replaces the Vita. Give it updated graphics/etc. About the only thing Muse could do with GOIO and Vita would be possibly a special Vita app that would function with the PS4 version. Sorta work as a 2nd screen to provide realtime info. Stat tracker sort of thing.
