Adobe announced PostScript level 3 last year.
(See http://www.adobe.com/newsfeatures/postscript3/transcript.html)
It is something different than PDF, though. And the company seems to have
different
objectives for PDF and PS..

I think that converting PDF->PS may not be lossy,
but if your documents have pictures in them,
or use special fonts, the converter might have to
embed them in the PS making it a bit bloated..
