Surely thats a colocasia of some sort?

Looks to me like it might be Alocasia reticulata. You could check the Agri-Starts site--I find their pictures quite helpful.

Definitely not A. zebrina reticulata, but does look like it stands a very good chance of being the Scott #1, aka "Aurora". I expect there'll be a lot of names being used for this particular Alocasia as ebay sellers and others hope to cash in on the fact that the plant is not yet known commonly in the trade.
