While most speakers say they use Operator Product Expansion, there is a subtle, but important different to use "Wilsonian" one that depends on the scale. 
(a)The smart Wolfenstein parameterization was very successful. However, when our goal is to go for accuracy, we need a consistent parameterization; we have it.
(b) Broken U-spin symmetry is fine for spectroscopy, but not for weak transitions. 
(c) As LHCb had measured regional CP asymmetries in beauty & charm mesons, we have found some surprises. Now from the run-2?
(d) Challenges for beauty, charm & strange baryons.
(e) It is one thing to talk about diagrams, while understanding the underlying dynamics is often different.
