iPod Update 2004-04-28
Apple has posted , which supports all models of iPod and iPod mini introduced before April 28, 2004. This update is required to take advantage of new features in iTunes 4.5 and the iTunes Music Store. It also brings improved playback performance for all iPods and adds support for the Apple Lossless Encoder, to enable compressed music encoding at high quality to iPods with a dock connector.

before April 28, 2004?
Time to overanalyze every word Apple puts out there. This update works on all iPods and iPod minis introduced before April 28, 2004. That would suggest that today's conference call will introduce new iPods. :-)
