We consider flavor-changing decays of toponium Vt=3S1(tt)→bs+bs due to t-channel W exchange in the standard model. A new expression for Vt→bb′+bb′ (where b′ is a heavy fourth-generation Q=- 1 3quark) is derived and its consequences discussed. We also consider the possible effects of the t-channel exchange of both charged Higgs bosons and the diquarks/leptoquarks found in some superstring-inspired E6 models for flavor-changing toponium decays.
