"So…for those players that were using the Blu-ray version of Warhawk that *did* update to v1.1 today, we advise that you go to the XMB (cross media bar), and in your "Game Data Utility", delete your Warhawk game data. Once you’ve done that, just re-boot Warhawk and the game will re-install v1.0, allowing you to play with the 1.0 world again. And I know you’ll all ask this…it will *not* affect your stats or Save Data.

Also please note that this inadvertent pre-release of v1.1 *only* affected players using the Blu-ray version of the game in the US. All
other countries and products were unaffected.

Once more, we are very sorry for the unscheduled, unplanned, preview roll-out v1.1

We are still tracking the end of October for the "real" deployment of the patch and, as always, we will keep you all posted!"
