Take a stroll on over to Apple's downloads page and peek at the 5th entry under Top Downloads. What you will find is an entry for iWork '09 -- which has yet to be announced.
We currently don't have any information available as to what changes would be present if iWork or iLife were updated. However, you can bet that if the Philnote features any dazzling effects not previously seen, they are likely a part of the updated suite.
Given that Apple is so secretive this seems like quite the slip up. While not featured in our rumor roundup, we would not be at all surprised for an update to both the iWork and iLife suites to be announced. If you have any hot features you'd love to see in an updated iWork or iLife suite throw them down in the comments.
Thanks Nick for sending this in!
