Reasons :-
i) It will not goes down for 2 days. If it is a tech problem, it should have been fixed.
ii) New google directory (alpha) is already hiding PR bar. e.g. [directory.google.com...]
iii) [toolbar.google.com...] has replaced an image without PR bar.
In short, it is not Google responsibility to inform wrong doers so they can prepare themselves.
Google do not (did not?) provide the PR tool for "wrongdoers". They provide it as a service to their users and they advertise it as such on their website. It is supposed to be a way of gauging the quality of websites.
Google still says, "Wondering whether a new website is worth your time? Use the Toolbar’s PageRank™ display to tell you how Google’s algorithms assess the importance of the page you're viewing."
If they have pulled the plug on PR they would do well to remember that PR can have another meaning, i.e. Public Relations. If this is just a glitch or an update they could help their own PR by providing their users with a status report on their home page to let them know that their search engine is not currently doing what they claim that it can.
All this would take would be a one liner, "Our PR tool is being updated and not available at present", or something along these lines. No one would fall out with them for that. If it is being removed then they should have announced this before the event.
ii) New google directory (alpha) is already hiding PR bar. e.g. [directory.google.com...]Isn't that just the alphabetical order? :-) The link to order in PageRank order is still on that example page, and shows the PR bar, with a toggle for the display order to go between PR or Alphabetical ordering. I had merely assumed "alpha" meant the ordering, given it appears as the URL when you request alphabetical order, and not a new version. Did I miss a trick here?

This indicates googles's strategy shift!
Busting the links selling this way preventing the most "unnatural" way of acquiring link popularity is something Google has been trying to do since it went IPO.
Myself I won't change anything in linking strategy for my projects - presence in cache, relevance, "hilltopness" in my area, age or "unsandboxedness" of the link partner's domain is what mattered to me for quite a while a lot more that just some green light on the bar.
