In 2001 the Tevatron run II began, after a five year period of
significant upgrade of the accelerator itself and of the experiments CDF and
D0.  After a detector commissioning run, the CDF experiment is now taking
high quality data with all subsystems functional.  We report in this talk
the first preliminary CDF results on top quark and W/Z boson properties,
based on run II data.  The top quark, discovered in 1994 at the Tevatron,
has proven to be a very interesting particle.  Its properties allow to
perform stringent tests of the Standard Model (SM) and to search for new
physics through a deviation from SM predictions.  We give here some
expectations of what Tevatron run II will ultimately provide to our
understanding of matter.
