"The next version is slated to roll out in September to one of the three main credit reporting agencies — Equifax Inc., Experian Information Solutions Inc. or TransUnion LLC — with the other two agencies receiving the new version some time in 2008."
The way I understand it is that only one of them will stop using AU in Sept and the other 2 sometime in 2008. Everyone has been making it sound like all 3 will stop this Sept. Which isn't true.
I think the discussion I remember was in the middle of a thread that might have been about a different subject, so it would have been hard to find.
Fair Isaac and the CRAs probably want to wait until August to announce details, otherwise there might be more panic as consumers (and possibly the credit rental organizations) try to purposely shuffle AUs to the two CRAs that will not use the formula until 2008.
Or it could be that there are some negotiations still going on, and perhaps the September CRA hasn't been determined yet.
