It's been an extremely tough time for alot of XBOX players most recently with Activision(who publish Lucasarts titles in Europe) not planning ahead, leading to massive shortages on the last few key Lucasarts releases.
Battlefront, KOTOR II and Mercenaries have all had shortages, leaving key retailers out of stock over launch weekends and waiting days, sometimes weeks to be restocked. With this in mind, just a friendly warning to you all to pre-order Republic Commando, otherwise it *could* be another case of being out of stock!
