  After some recollection of the implications that top quark and Higgs boson
properties determination have had on each other, we discuss recent and future
expected progress in the study of the top-Higgs sector. In particular we
discuss some results concerning new physics states interacting with the
top-Higgs sector, the impact of measuring top-Higgs interactions accurately to
determine the Higgs boson self interaction, the CP nature of the Higgs boson
and possible detection of flavor violating interaction at levels comparable
with the prediction of viable new physics models.
