Future B Experiments from The BTeV/LHC-b Perspective

Many measurements are necessary in the program of studying mixing, CPviolation and rare decays of b and c quarks. These measurements require largenumbers of B^o, B_s, B^- and D^{*+} hadrons. Fortunately, copius production ofparticles containing b and c quarks will occur at Tevatron and the LHC. Thecrucial measurements are described here, as well as the design of the twoexperiments, LHC-b and BTeV, that can exploit the 4-20 x 10^{11} b hadronsproduced every 10^7 seconds
