Well placing rel="nofollow" on existing links on a site would impact several things.

Only part of which is strictly PR related, depending on how Google looks at things the related link text should be made moot, the page that is doing the link just had an update done to it, and the page linked to should have also lost an IBL. So could this affect ranking etc? Yup.
