Go to www.seriouszone.com They are the best place to look for Serious Sam maps, mods and news. Also, I wouldn't worry too much about what the upcoming DLC could/would be. Croteam are extremely active in their fourms and really take the fanbase's suggestions to heart. Much like Remedy did with the PC release of Alan Wake, all of Serious Sam 3's testing was done by members of the forums. Fans.
