Who will top the decathlon showdown in Daegu?

Following Ashton Eaton's latest frantic all-round workout the previous couple of days, carving out substantial PBs in all three throws and missing a fourth in the high jump by a whisker, who do you think will come on top when the decathlon giants line up in Daegu for an anticipated breathtaking battle for the spoils? Eaton himself, fresh from a world indoor record in the heptathlon indoors, Olympic champion Brian Clay who has got also vast experience on his side or defending champion Trey Hardee? It very much looks destined to be decided between the three Americans all things equal.
