Vita themes too eh? Didn't hear that bit, but I'd rather a Vita OS overhaul similar to PS4 (Won't happen). Well it maybe good, but don't really like the theme above. I'd be happy just setting different colours.
I'm fine with the blue, themes aren't really my thing. I really wanted them to announce some damn content management/sorting options for 2.0. I don't care what the UI looks like as long as it is still a mess to actually use. I just don't want them to take the folders route that everyone keeps crying for, as folders won't fix anything outside of turning one giant mess of a content bar into multiple not quite so giant but still a mess content bars that would have to be manually managed.
