The official specs have been leaked, and IMO this body is typical Canon intentionally crippled garbage:
No IBIS
No Eye-AF
8 FPS with no AF (5 FPS if you want AF)
1 SD card slot
No high framerate 1080p (limited to 720p? What year is this?)
By far the smallest EVF of all FF mirrorless at 0.71x (0.8x for Nikon Z, 0.78x for Sony)
"-6 EV AF" is clearly a marketing gimmick as they have to qualify that as with an f/1.2 lens instead of the industry standard f/2.8
Recycled low dynamic range Canon sensor
Pretty much worse than the Nikon Z bodies in every single way (AF performance remains to be seen). If they don't price this dirt cheap, this'll be an epic fail. But I'm sure people will still buy it on name alone.
