Not sure if this is old news or not, but I just ran across this article and spy photos http://www.leftlanenews.com/spied-2010-jeep-grand-cherokee-srt-8-facelift.html#more-7829
Interesting, but I hope they redo the entire body for 2010 not just a facelift. The addition of a 6.4L would also be nice. In those pics it appears the hood may change & the bumper cover looks to have more ground clearance. The rear bumper cover is not an SRT cover.
