I don't know, but I've always thought the different races should have different stats. Orcs should be the only race to have 100 strength, bosmers and kajiits would be able to have a max strength of only 80 but they'd be the only ones to have 100 agility ect.
Also, attributes are now gone. The way to differentiate each race is likely to come from race-only perks and race stuff from previous games.
