So it seems that Deep Silver announced the release date along with the gameplay trailer we've seen in the last couple of days! Looks like August 22nd for Europe and August 26th for North America.
Press release is as follows for those interested.
Also, Amazon has currently listed the game for $49.99 (US) and £39.99 (UK), which I have no idea if that's cheap or expensive for those respective regions considering I'm not from either!
