Papyrus has actually been released?
AFAIK MorphOS and AmigaOS 68K versions of Papyrus are currently available. We review the AmigaOS 68K version in Total Amiga issue 24.
If you're thinking of the announced OS 4 version, my understanding is that Titan got the required number of pre-orders (60 IIRC) but can't begin development until they get a OS 4 development system. There seems to be some argument over who should supply such a development system (and I'm sure the current lack of OS 4 compatible hardware doesn't help!).
