Free Splinter Cell Conviction content incoming news article
What these are is anyone's guess but the ticker which scrolls across the menus states 'Be sure to check back every Thursday for Free Splinter Cell Conviction content starting April 15th!'

This is great news and hopefully Ubisoft will continue to support the game for a long time after it has launched. Looking at the game, hopefully some more skins for Deniable Ops, extra weapons for use across all game modes, and even some additional maps. We've heard that the Japanese version of the game includes the Hunter mode map '3rd Echelon HQ', so hopefully this will be one of them. Maybe we'll also see some avatar items as well. Either way, we'll find out on Thursday, stay tuned.
