I sketch novel directions, namely attempts to deal with quark-hadron duality in a (semi)quantitative way and to develop a QCD description of two-body modes of $B$ mesons. After commenting on predictions for $ε^{\prime}/ε$ and CP asymmetries in B decays I address indirect probes for New Physics in $D^0$ oscillations and CP violation, in $K_{μ3}$ decays and electric dipole moments. I describe in which way searching for New Physics in B decays provides an exciting adventure with novel challenges not encountered before.21 pages, LaTex, Plenary Talk given at ICHEP2000, July 27 - August 2, 2000, Osaka, Japan; some typos and references correctedHigh Energy Physics - Phenomenologytext
