Interbike was full of great looking bikes this year. I like Fair Wheel Bikes and Crumpton take the cake for the most lightweight though. They had a 8.88lb carbon Crumpton road bike on display sporting some highly exotic parts. They do atest though that the parts are all relatively proven models that can be ridden pretty hard without failure. Check out the full article on Bike Rumor for all the details on this feathery light build.
