It probably wasn't on your PAX wish-list, but a sequel to A Kingdom of Keflings is coming to Xbox Live Arcade at the end of 2010. Titled 'A World of Keflings, the announcement was posted over at Xbox360achievements.org.
Multiplayer appears to be the main hook of this sequel, with players being able to manipulate their world in a number of ways; climate, culture and resources are all customisable. The sequel again places your very own Xbox 360 avatar into these environments, where you'll find more of the same content that made the original adorable.
A World of Keflings is due to be released sometime before the end of the year. You can take a look at the trailer below.
