Guerrilla hints at Killzone Mercenary for 2013

On a PSN POST, Guerrilla seems to think that the Vita's next attempt at an FPS action game will arrive next year.

"But the biggest highlight of the year was being able to welcome SCE Cambridge Studio into our fold. We’ve officially become a multi-studio company! Guerrilla Cambridge – as our new sister studio is known – is working hard to ensure that Killzone: Mercenary will be the ultimate handheld first-person shooter experience when it launches for PlayStation Vita in 2013.
The team is intimately familiar with handheld game development, having previously worked on titles such as LittleBigPlanet for the PlayStation Portable, and they’ve done a phenomenal job adapting the Killzone 3 engine to the PS Vita platform.

With Killzone: Mercenary on the way, 2013 is gearing up to be another big year for Guerrilla – quite possibly the biggest since we released the original Killzone way back in 2004. We’ll have more details for you at a future date, but until then we hope you share a wonderful holiday with your loved ones, and we’ll see you in 2013."
