What are my chances to get PR 5-6?

As per my very little knowledge, u wouldnt be able to cross PR3 with free directories in the next PR update.
A PR is good term for the people selling ur website, but most of us know, it doesnt give u much return
Wat u should concentrate on is SERPs, n we all know its significance.
Of wat i heard here so far, next PR update is expected in Mar-April. But nobody tell for sure....

 

High PR is good for a few reasons, not least because

1. It gives you far higher link partner trading power. You can start picking and choosing your partners.

2. You can sell links if you wish for quite a tidy profit, if whatever you are doing isn't working out.

3. Your domain name becomes a very nice piece of real estate.

 

I would say none. Or very slim you need great links and a mix
