The current state of the art in top-pair production is based on threshold resummation on top of the exact NLO result. We will examine the role - and the limitations - of the soft-gluon approximation in describing precision top-pair production at hadron colliders. We will demonstrate that the only way to substantially improve our knowledge of this observable is through fixed order calculation at NNLO. The status of this ongoing calculation will also be presented.
