Deus Ex: Human Revolution has been added to their stable of games, and pre-ordering the game will grant bonuses.
Pre-ordering the regular version will knock $5 off the price tag and also give you a free copy of the original Deus Ex. Getting the Augmented version will slice $6 off that price, cutting it from $59.99 to $53.99, as well as granting a copy of Deus Ex, a Making Of video, some books, the game soundtrack, and other stuff.
You can check out the OnLive page. OnLive allows you to purchase virtual games without worrying about system specs, as the game streams through OnLive to your monitor.
