I would imagine it has in body stabilization of some kind, for the same logic (24-70/4 does not appear to be stabilized in the lens).
However, additional moving parts are a source of possible failures / repair bills later on and in-camera stabilization is linked to overheating in extended video recording in hot conditions and increase in long exposure noise over prolonged periods of use. Furthermore I would imagine there to be some increase in power consumption when the sensor has to be actively held in place at all times.
