I know one or two people in this forum who have made to PR5 in 1 update and another guy who has made to PR6 from another forum . If i manage to get high PR oneway link and whatever is required in order to get PR5 ...will google consider giving my site PR5. or time is also a factor ? What i meant to ask was is Time factor for PR ?
What will you do if the next update will be in 120 days? You cannot get a PR update when you want. You get it the same time we all get it.
Yes, you can obtain pr 5 on the next update (which is suposed to be in april - but nobody knows the future), but it will be difficult. You'll need a lot of quality links and SEO. And quality content. It's hard, but possible.
We can't know exactly how google algorithms work. However, if we obtain a lot of IBLs and we keep our site clean, we might get a good pr, a good ranking. But we have to work hard. "For a PR5 all you need is a PR7 backlink.. or to be sure get 2 PR7s." you can't be sure of that. Btw, it costs a lot...
I think you can get a PR 5 in the next update if you manage to get a PR7+ link. But I dont think it worth the price you pay for it.
