My webstie was penalized by Google because of paid links. I file a reconsideration request recently and they updated the PR to 2. Now the update is expected, so, there would be some changes in PR of my website or it will remain the same?
as sturat said, only google knows that best.
it all depends on the quality of the backlinks + the number of outbound links on those pages
One of my sites, a blog, got a PR 3 on the basis (as far as I can see) of a single reciprocal link to a site with related content. The other site's link to me was deep in the content of a page, and my link to it was on my home page.
