Via Ripten:
"Gamers spoke, and SouthPeak Games listened to every word they had to say. In addition to a playable demo that will be hitting XBL tomorrow, the crew at SouthPeak has been hard at work on an update to address the feedback they received from players. We have been told that the update will be available soon, and when it comes down to it, you really can't ask for much more than that."
Ripten has a list of some of the improvements that players can expect to see in the update.
