This article in Geoff Keighley's "Behind the Games" series: http://www.gamespot.com/features/btg-daikatana/, provides a more complete account of the story of Daikatana. Without Eidos, and had Romero been as rich as 3D Realms at the time, I am convinced that Daikatana would have ended up as another DNF.
Daikatana basically did end up like DNF, although it was finally shipped after nearly three years of delays to critical disappointment. The time frame of the original was similar to DN as was the hype.
