This handout was "confidential" when handed out 1 year prior to this above and IIRC it was indeed describing DE.
AmigaDE was born in Amino - outside Amiga.Inc. Your paper is from Amiga.Inc and describes its plans for Amiga NG. Considering this paper is from February 1999 it was created even before Amiga MCC cancellation. It has nothing common with later Intent based AmigaDE plans.
Plans of Amiga.Inc (Gateway2000) and Amiga.Inc (Amino) seems to be similar, but not the same. You probably misunderstood the difference between both projects.
