Hall of Famer

I was only partially joking on the M, but for the record, yes, the M's sensor is the same as the latest Rebels AFAIK, and that is a generation newer than the 7D. I could be wrong, though.
No Canon expert, but my understanding is that it's the same sensor. Canon didn't do a "generation" of sensor very often in this period which was a criticism of them -- but the sensor was good enough it really wasn't necessary.
That being said, manufacturing improvements might have made the later sensors somewhat better.
