There are several long-standing discrepancies between observables in b->c semileptonic decays and their Standard Model predictions. There is also a long-standing tension between inclusive and exclusive determinations of Vcb, the latter being obtained from these same decays. At the same time a wealth of new experimental information in these decays is becoming available, and thus it is a challenge to the theory community to keep pace with these developments. Here I will review the state-of-the-art in lattice QCD simulations addressing these issues. After reviewing the status of B->D(*) form factors and measurements I will discuss in more detail new results from HPQCD that treat the ‘b’ quark fully relativistically.
