The point SeaFox was trying to make was that Panther for $129 (or 10.4 for that matter, if it is also $129) is much better value for someone like him who only has OS 9 than someone who has Jaguar (i.e. the previous version). They currently don't run Mac OS X (OS 9 has more similarities with Win 3.1 than OS X IMO) so they are not really 'upgrading' in the true sense.
Also, an upgarde path may help sell more copies of the previous version prior to the next one's release. Yes, Apple doesn't announce when the next version will ship until a month or so before, but there's a lot of users who would stay clear of paying $129 for Panther when they know that 10.4 is imminent (e.g. from MacRumors, other rumours sites, Apple's own sneak previews). (Remember, all the clueless switchers, of which I am one, would have bought their new Mac and had Panther for free, so it's only the people who were established Mac users who would be in the market for buying Panther/10.4 retail).
Regarding metadata, so it sounds like it's just a faster way of searching for files
