There have been several different announcements, but only a few actual products. First, the harddisks were announced as 2.4GB and 4.8GB, then as 2.2GB and 4.4GB with CF (1022C/1044C), ATA/IDE (1022A/1044A) and USB 2.0 (1022U/1044U) interfaces. There is also product roadmap available, aiming at 16-20GB for end of 2005.
