Yeah, basically all minor updates before the new version comes out in 13 or 14.

The nav system update is a welcome one for new owners as gm is finally catching up with the rest of the 21st century ... although there's no reason to get excited obout that until the CUE system gets implemented across all platforms and models.

The coolest update is on the non-hybrid premium and platinum escalades with their new uber sweet looking double exhaust through the rear bumper ... someone should retrofit that.

 

I believe changes to the hybrid drivetrain - i.e. the "4-mode" hybrid, are slated for 2015 at the earliest now.
