It is rumored that the Canon new full frame camera Canon EOS 3D will have a high 52 MP sensor more than 46 MP.
According to the NL, it will be based on the 4.2 micron pixel design of the Canon EOSĀ 70D/7DII, not the long-in-the-tooth 4.3 micron design of the 18MP APS-C sensors. So, when translated to full frame, that totals about 52MP.
