Seems that this will be the official thread of the next PR update also , i think PR will be updated within 2-3 months

Few here i) Content ads ii) Affiliate iii) CPA iv) direct product selling v) getting ads purely based on traffic vi) Membership fee vii) Selling ads in your newsletter to your site users viii) Offering your services list quite goes on and on...
You know, this thread almost gave me a heart attack - started to feel blurry as I thought the PR was updated and I checked it for my main site just an hour ago and it was still 0 >.>.
Yea, I use iwebtool to check backlinks, pr, ect... My site will go from PR1 => PR3 (3.4) My one client's says will go from PR4 => PR5 (4.7) But like you said....prediction tools are not accurate, but they are cool to look at.
