I loved Sleeping Dogs, so I'll surely get this game. It would be awesome if the made a Vita version :P Vita need a quality open-world game like this. If it can't get GTA, new Sleeping Dogs would be the second best thing.

Don't be surprised when they announce it as an iOS in 2014.  Square Enix is publishing the  game, after all.
