They forgot to show Strider's sword being made whole again!
My hunch is that they will show the reforging of Narsil/Anduril in The Two Towers, and probably have Arwen deliver the sword to Aragorn just before or after the battle at Helm's Deep. Anduril does not become crucial until The Return of the King, where it functions as a legitimizing symbol of Aragorn's ancestry and claim to the throne of Gondor. Plus having Arwen deliver it helps solidify her larger role in the movies.
