During yesterday's Media announcement involving the U2 iPod, iPod Photo, and International iTMS stores, Steve was using what appeared to be a version of keynote with features not yet released in the wild. An independent photoblog shows the images and transitions. Given Steve's propensity to use only Apple-made items when possible, it's doubtful these were made with 3rd party plugins.

Keynote 2.0 has been rumored to be on the update slate for a few months.
