But not necessarily better quality. Fellow Badlander MCD made good use of Snapz Pro to capture a longer slice of the keynote stream last night, including Jobs' introduction of Jones, and Jones' introduction of Halo.
The quality is nowhere near as good as the now widely distributed Gamespot movie (easily identified by the large G logo slapped onto the work of others... isn't that illegal? ':), so if you're wanting to watch the game, don't download this one. If you're interested in the introduction of the demo and subsequent response, then take a look. A speedy connection is a plus, too.
