My suspicions are confirmed, the US will indeed be getting this car in the next few years, in quite a few different versions too. As quoted from wikipedia:

The Epsilon II will be used in the following vehicles:

2008 Opel Insignia
2009 Saab 9-5
2010 Buick LaCrosse
2011 Saturn Aura
2011 Pontiac G6
2012 Chevy Malibu
