Many people noticed some unusual Keynote presentation effects in Job's recent keynote at MacWorld (e.g. the small text exploding above). Now Brian Peat over at KeynoteUser.com has gone through the keynote with a fine-toothed comb, identifying a bunch of new stuff, like path animations and lots of explosions that cannot be done with Keynote 3 (editorial note: explosions = good). Since it stands to reason that Jobs might just have access to some pre-release version of Keynote, it's a pretty safe guess that this is a preview of what's in store for Keynote 4. It's an interesting read and will probably have heavy Keynote users salivating for iWork '07.
