If you wait that long it might be a good idea to make sure your new pages are linked from your homepage, so Googlebot will have a better chance of discovering them late in the cycle.
There is a good chance the high PR pages will get indexed sooner than low PR pages. High PR pages or other pages with something Googlebot has an interest in have a high chance of being reindexed later in the cycle. If you update the links to the page late googlebot may not give you credit for all of your links. And if the page is late and gets spidered before the content ... you wont get credit for the content googlebot does not see.
