From the experimental branching ratios for B- --> ρ0 l-νl and D+ --> \overl K*0(\overl K0) e+ νe one finds, in the Heavy Quark Limit of HQET, |Vbu|=(8.1± 1.7) x 10-3, larger but consistent with the actual quoted range (2 - 7) x 10-3. In the same framework one predicts for R(B --> K^*γ)=( 2 ± 2 ) 10-2.
