Other than losing borrowed credit history via AU accounts, FICO 08 will help those whose credit has been clean (mostly) in the last two years, as well as those whose credit mistakes were sort of limited. Unfortunately, I haven't seen anything more specific than this.
I'm a bit anxious about this myself, as I have lates on 3 different accounts, not just on one card or loan for instance, so I sure would like to know more. But FWIW, it might well be years before 08 is being used on a regular basis. Lenders are surprisingly cautious, especially after the mortgage disaster of the last year. I doubt anyone will want to be the first to abandon a known formula for 08.
How recent are your baddies? A clean recent track record will help you a lot.
