I know some sites that have a few tens of thousands of backlinks, among which a good amount of high quality backlinks, from PR6 to PR8 sites, and they have a PR4, you can't say. it can depend on the age of the domain too (but this is a minor criteria). and don't forget PR is updated every 3-4 months only, so you may have to wait before seeing the effect of high quality backlinks.
Why do you care about the PR ? is just a number And only google knows the answer the rest are simple supositions
probably PR2-3 .. again depending on the quality of ur links.. could be upto PR6 even hope for the best
wow....you must know someone on the inside... I have 6,000 links to one site and I'm still a PR4, Predict what my PR is going to be
Everyone in this thread that has given you a number is blowing smoke. There is absolutely no way that anyone can answer the question you asked beyond saying 'somewhere between 0-10'.
I take it you are being sarcastic, the site in question has 500 Google backlinks, not regular backlinks, I will spell this out for you: Any website with more then 500 Google backlinks using the link: command on Google web search will get at least a PR4!
S**t I take back what I have previously said in this thread, I didn't realize he was on about web master tools, could be anything, apologies.
