A Send-off after Dif06: What Do We Need to Know to Understand More?
  After a brief look back at the roles played by hadronic machines and $e^+e^-$ colliders I emphasize that continuing dedicated studies of heavy flavour transitions should be central to our efforts of decoding nature's `Grand Design'. For studies `instrumentalizing' the high sensitivity of \cp violation will presumably be essential to identify salient features of the New Physics anticipated for the TeV scale and hopefully discovered directly at the LHC. An $e^+e^-$ Super-Flavour Factory would provide the optimal platform for such a program.
