The X1000 and the Sam460ex were both running beta flavours of AmigaOS 4.1 with all sorts of features enabled which have not shipped yet.
I suppose you could say it was a "leak" but if we really wanted to keep it all secret the boxes wouldn't have been running a beta versions. Nice to see some people were paying attention.
Underneath, the OS has been improved as well but those changes are always much more difficult to visualize like the USB 2.0 support.
