Face it, on BD any number except 2010 would indicate a fake. 2010 is the only number that is logical.
Besides, the BD looks very much like the Llano on the print on the heatspreader, and it's the same source. At the same time the Llano seems very legit since it's the first sighting of the new socket, it doesn't look photoshoped. So, I think we have strong reasons to believe both are the real deal.
