As m42 pointed out, the bad news is that no-follows may soon bleed PR.
I read Matt's previous comments on this issue and quite frankly it doesn't make any sense that ANY PageRank should the bled off or passed with a nofollow. The original idea behind the nofollow attribute was supposed to be that the link did not count for anything.
This is potentially a significant issue for WordPress blogs or any sites that have been automaticaly inserting nofollow attributes. I suspect it would increase the amount of spam comments with blogs.
I also wonder if a link that passes some PR would inherit some of a penalty applied to a page it links to. The nofollow attribute was also supposed to prevent the inheritance of penalties, as well.
