Apple leaked the next Devices via Logfiles in popular apps (again).[1]
One funny things (also again) is the naming of the Products.
M3 .... okay
M3 Pro .... yes, for professional Users I guess
M3 Max .... okay, this is the maximum of performance
M3 Ultra! ... because, when Apple say maximum they mean something unscientific I guess^^
