Could it be that it was 527 days since the previous update which is, by a wide margin, the longest delay between MBP updates ever?
If Chevy named the majority of their cars Malibu (1/2 ton truck), Malibu (3/4 ton truck), Malibu (2 door sports car), Malibu (4 door electric sedan), Malibu (4 door full-size sedan) then they would have the largest amount of Malibu's sold ever too.
