  The last two years have seen an impressive improvement in the determination
of $|V_{ub}|$, especially from inclusive decays. The error on $|V_{ub}|$
measured with inclusive decays was reduced from 18% (PDG 2004) to 8% (PDG
2006). This progress is a result of combined experimental and theoretical
efforts. In this talk, the theoretical framework (BLNP) that enabled such
progress is reviewed, as well as other approaches to an inclusive determination
of $|V_{ub}|$ (DGE, $M_X-q^2$ etc.). The prospects of improving $|V_{ub}|$ are
discussed, addressing issues of weak annihilation, implications of leptonic B
decays, and determination of $|V_{ub}|$ with exclusive decays.
