I ran across this article outlining some of the differences in the upincoming FICO system. There seem to be many benefits to those who had a couple slip ups a while back, however it's stated the penalty for maxing out credit cards is increasing. Lots of good information and definately worth a read if you haven't read up on it yet.
"Two people with the same FICO score currently could see their scores diverge under the new system. One possible reason: FICO 08 gives more points to consumers who maintain a variety of credit types, such as credit cards, a mortgage and auto loan, because it shows they can manage payments on different kinds of loans. On the other hand, the new scoring system penalizes to a greater degree borrowers who use a high percentage of their available credit."
