Super Icon Writes: The Vita is a really nice machine, with potentially superb graphics performance. We really wanted to utilize this as much as possible – with nice shaders, real-time shadows, reflections and so on. We did this – but an issue we hit was that the Vita just isn’t as powerful as say a PS3 or Xbox, so it required a fair few months of code optimisations to get decent performance. It was hard-core for a developer as small as we are, but we were delighted with the results and how nice the games looked on the Vita.
Also, can't they ask Sony? Sure, they might force the developer to make it exclusive, but Sony would fund them.
If it's something ambitious like that then people will support it on Kickstarter. At least I would.
