Seems like you misunderstood something. There are two patches: one for PC and one for... PS3. And it's not like you can't pirate it on Vita too. The game will be pirated anyway, regardless of the platform. The only way to minimize the losses it to release the game on all platforms simultaneously. And no, it's not about "revenge" or something, people just want to play the game on their preferred platform as soon as possible.
