That's the million dollar question. Some say in theory that it may have value in rankings as a hint towards overall relevance.
The bigger question is in finding out what drives the high bounce rate. Is it relevance issues with the keywords searched for or does it deal with usability issues of the site.
Not yet, but the potential is there as Google attempts to provide better results. I droll over that prospect... That might put the hurt on all those social media site links!
It may happen because Google wants to provide quality results. If you have a high bounce rate you should fix that problem before you worry about ranking.
