The 3D documentation isn't available yet to the public either, because IP review apparently turned out to be much more complex then anticipated. Much to the annoyance for everybody involved, including explicitely those poor guys at ATI that have to review them.
Bottom line is: we will eventually get there, but even with ATI's great help it's more difficult than anticipated. The programming itself isn't that bad (though definitely much more complex than with r5xx), it's the tiny little details that bite you.
Hope they keep up the excellent work though!
