Looks like we European noobs will be getting Warhawk via the PSN around the same time as the North Americans, according to ThreeSpeech:

This is now confirmed for PSN release on August 28 for £19.99 UK or €29.99. The Blu-ray/Jabra headset bundle will follow at retail on September 21 for £39.99.

So next Tuesday it is! I’m still undecided about this. I’m leaning more towards the BD version with the Jabra headset but I’m still not 100% sure.
