Konami Digital Entertainment has announced that it will exchange correctly printed cards for misprint versions of the 3-D Holographic Rare card, Elemental Hero Chaos Neos, from the recently released Yu-Gi-Oh! expansion, Gladiator's Assault.  The misprint versions are labeled Rainbow Dragon instead of Elemental Hero Chaos Neos. 

Konami is offering to redeem misprint cards for the correct ones by mail or at major Yu-Gi-Oh! TCG events.  Of course, it's probably more likely that the misprint card will be collected and escalate in value, making the odds of redemption low.  There does not seem to be an established price on eBay yet, with only a handful of misprint cards available at widely varying prices.
