Recent theoretical developments in CP violation in the B system

After a brief review of the present status of the standard methods to extract CKM phases from CP-violating effects in non-leptonic B-decays, an overview of recent theoretical developments in this field is given, including extractions of γ from B→πK and Bs(d)→J/ψKS decays, a simultaneous determination of β and γ, which is provided by the modes Bd→π+π− and Bs→K+K−, and extractions of CKM phases from angular distributions of certain Bd,s decays, such as Bd→J/ψ ρ0 and Bs→J/ψφ.
