Note that we're referring to TBPR (Toolbar Page Rank) here. Matt made it clear that Google continues to keep PageRank updated internally... it's just the Toolbar that isn't changing.
I got the sense, from Matt's statement at PubCon, that... for reasons viral's post suggests... Google might be rethinking the question of whether to show TBPR at all. Not anything Matt said specifically... just the lack of importance Google seems to be attaching to the display.
That said, I am seeing enough reports that Google is using it TBPR selectively to suggest Google also finds the display useful in some cases.
