Nathan Drake personally endorses Pepsi. And he's got a whole bunch of Uncharted 2: Among Thieves PS3 bundles to give away if you buy specially marked 12-packs of Pepsi. The bundles include a PS3 Slim, alongside both Uncharted: Drake's Fortune and Uncharted 2: Among Thieves.
Get buying Pepsi now. It's officially better than Coke anyway.
