Your desire to criticise Canon really does make you unable to read. Canon say this is an adapted 5DIV sensor, so whichever way you look at it is is a new sensor.
yes, they sell newly made sensors, not used ones. Other than that nothing "new" about that 5D IV sensor. They just slapped slightly different micro-lenses on it it to match RF mount geometry. That's really all they did. No BSI, no improved readout speed, zilcho.
