Not only is Incognito hard at work on Warhawk
1.1, they're working on another future patch, 1.2. This revision will finally take care of that dreaded "tank" glitch, which according to the PlayStation.blog also affected turrets and Warhawks. Additionally, the patch will include a new integrated Store interface, so you can download upcoming Booster Packs from within the game.
The 1.2 update also adds rumble support for DualShock 3 controllers. Of course, this will be a moot point for most -- the controllers won't be commercially available in the US this year anyways.
So when is this magical update supposed to appear? In December. Until then, we'll have to patiently wait for patch 1.1
