Colt fans don't think that I am being negative towards Colt, because I am a fan -- but I didn't see anything exciting or new at their booth. I can confirm for 10mm fans that the Delta Elite (the current O-frame model) was there again this year. Missing again, was the Enhanced O-frame/XSE displayed previously. I didn't think to ask about it.
Here are a few pics that I snapped while I was there (yes, all from the Colt booth):
