Determining Vcb and probing HQET in exclusive semileptonic decays:
 Prospects for B>D*lnu decays:
 With what precision can F(1)Vcb^2 be measured with 500fb1?
 What are the prospects for improving the calculations of F(1)?
 How much improvement can be expected in FF measurements on B>D*lnu?
 Is it feasible to experimentally test the q2 dependence of R1 and R2?
 The BF for B>D*lnu is needed as input to many other measurements. How much can it be improved, and when?
 Prospects for B>Dlnu decays:
 With what precision can G(1)Vcb^2 be measured with 500fb1?
 What are the prospects for improving the calculations of G(1)?
 What are the prospects for FF measurements on B>Dlnu?
 The BF for B>Dlnu is needed as input to many other measurements. How much can it be improved, and when?
 Higher mass B>Xclnu decays:
 What can be learned about Ds production in nonstrange SL B decays?
 The BF and FF for B>D**lnu is needed as input to many other measurements. How much can it be improved, and when?
 Other approaches:
 Given a 500fb1 data set, how well can one measure Vub/Vts using B>K*l+l and B>rholnu decays?
