The fourth generation can give the correct trend of S-Phi K0, S-pi 0K0 < sin 2 phi(1), as indicated by data, and the effect, being largely leading order, is robust against hadronic uncertainties. The effect on S-eta ' K0, however, is diluted away by hadronic effects, and S eta ' K0 similar or equal to sin 2 phi(1) is expected. The near maximal arg (Vt ' sVt ' b)-V-* <= 90 degrees that is needed could resolve the unequal direct CP violation seen in B -> K+pi(-) and K+pi(0) modes, and is consistent with b -> sl(+)l(-) and B-s mixing constraints.
