...has shrunk to:

"Aladdin 4D 6.0 will work native on the platforms listed below.
OS X Lion
iPad"

Also:

"Aladdin 4D 6.0 will be available for OS X and iPad only"

Seems Linux has been added again:

"To help expedite the release of Aladdin 4D 6.0 we are limiting the platforms it supports. We know this will come as bad news to many of its fans on the Amiga but the long release cycle is doing no one any favors. For version 6.0 Aladdin 4D will only be shipping on Mac OS X, iPad and Linux."
