Well the Cap movie unfortunatley didn't really do much to credit or discredit the theory. We were teased by the possiblility that Armin Zola might be the clairyvoyant but he was apparently confined to a data center, and nothing more

I don't think Victoria hand is the clairvoyant. Shady yes, taking orders, yes, but I believe the Shield mainframe AI is the clairvoyant and eventually will make a body for itself and become Ultron
