Last month, Canon Rumors reported that a 32-megapixel APS-C sensor was on the way from Canon. Now it looks like that information has been confirmed, according to a Taiwan certification agency.
The document seems to be mostly in Chinese, according to Google Translate, and mostly seems to relate to a new wireless module. But it mentions that it’s destined for a new Canon sensor. DC126801 appears to be a new 32.5-megapixel sensor that could be set to go into either a 7D Mark III or 90D DSLR.
