The "wrong sign" B → φ K_S mixing-dependent CP violation as observed by Belle in 2003 is 3.5 sigma away from Standard Model expectations. If verified, it will be the long awaited New Physics. It suggests a large s-b flavour mixing with accompanying CP phase, and involving right-handed interactions. The observation of sizeable transverse polarizations in B → φ K* also suggests new physics. The experimental situation is reviewed, and a possible theoretical interpretation is given. In a general framework of approximate Abelian flavour symmetries with SUSY at TeV scale, a flavour-mixed, right-handed "sb" squark can be driven light by large flavour mixing, bringing in a unique new CP phase, and satisfies all necessary criteria. The impact for Super B Factories and comparison with hadronic machines are given. Direct search and impact on Colliders would also be discussed.
