If you're curious about Omerta: City of Gangsters on the Xbox 360, a demo is now live. The game itself is basically a bare-bones simulation similar to the Tropico series mixed with portions of gameplay similar to XCOM.
There's also an update coming "in the next four to eight weeks," that will feature a number of improvements to the PC and 360 versions of the game, like the addition of an Iron Man "no combat save" difficulty mode, and an overhaul of the cover system.
Of course, if you already read my review, you're probably already turned off by this fairly disappointing release, and the updates don't seem to fundamentally change the game.
