it says stuff about home

Yeah Baby…So our HOME integration is coming along nicely and this update includes a great, and much needed feature for Warhawk. With the release of v1.3 patch, players will be able to form groups, meet in their apartments, discuss tactics, and then launch a game of Warhawk…all together!

When you're in your apartment, all you do is whip-out your virtual PSP, select 'create game' and pick Warhawk. From there, you get to start your own player server, pick a game rotation, set server options and then…BAM !! Launch Warhawk with all of your friends!! You can also pick to not make your game viewable to the other Warhawk players around the world, or you can make it a 'public' game that puts all of your friends into the server together, and leaves open slots for other global Warhawk players join.

Games launched from HOME show up in the global games list in an attactive gold color.

I noticed nothing about a release date, but stil it gives us hope.
