Pretty sure the Genesis did sell 40 million guys.
33 mill is the official number, I remember seeing it from Sega themselves a few years ago. I think it's also described in the Console Wars book. 49 mill for the SNES, 33 mill for the Genny.
The N64 wasn't a "failure" altogether per se, but it is considered a failure because it was expected to be no.1 and it basically caused the end of Nintendo's leadership in the traditional console sphere and led to the rise of the Playstation as the dominant brand in the business.
