Sorry zackman, this is what it says in the release:
The upshot is that we are taking orders for both the 600MHz G3-based AmigaOneG3-SE, and the 800MHz G4-based AmigaOne-XE, starting at the WoA-SE show on 2nd November 2002 - for delivery before Christmas (and, yes, for the cynics out there, we really do mean Christmas 2002!). A 700MHz G3 (750FX cpu) version of the AmigaOne-XE will be made available - at reduced cost - early in 2003.
This means that the 600MHz G3 and the 800MHz G4 will be delivered before christmas, and the 700MHz G3 in early 2003. The G4 *is* the -XE version. If you're going to accuse someone of not being able to read, make sure you're not guilty of that too!
