  I shortly review the present status of the theoretical estimates of eps'/eps.
I consider a few aspects of the theoretical calculations which may be relevant
in understanding the present experimental results. I discuss the role of higher
order chiral corrections and in general of non-factorizable contributions for
the explanation of the Delta I = 1/2 selection rule in kaon decays and
eps'/eps. Lacking reliable lattice calculations, the 1/N expansion and
phenomenological approaches may help in understanding correlations among
theoretical effects and the experimental data. The same dynamics which
underlies the CP conserving selection rule appears to drive eps'/eps in the
range of the recent experimental measurements.
