The last two years saw an impressive improvement in the determination of Vub, especially
from inclusive decays.  The error on inclusive Vub was reduced from 18% (PDG 2004) to 8%
(PDG 2006).  This progress is a result of a combined experimental and theoretical efforts.

In this talk, I will review the theoretical framework (BLNP) that enabled such progress , 
as well as other approaches to inclusive determination of Vub (DGE, Mx-q^2 etc.). I will 
also discuss the prospects of improving on Vub, addressing issues of weak annihilation, 
implications of leptonic B decays, and exclusive determination of Vub.
