This is incorrect. Please see the quote below from the Scrivener developers:

Windows. Scrivener will now start-up at least twice as fast as before and
feel much snappier in general.
We have fully automated the build and packaging for Linux. We have found a
solution for implementing a pdf reader (a key missing feature for Linux);
although this will not make the 1.1 release - but it will come. We have
added Markdown and MultimMrkdown compile support allowing plain text
exports to: xhtml, opml, odf and Latex tex format. We have also
implemented MathML support, as the Windows MathType is not supported on
Linux. There's a stack of bug fixes and a few new features.
Linux 1.1 will be released a week before the end of March, so folks will
have a full week before expiry. The new beta will run until end of June
2012 i.e. another 3 months.
There is no way, we are dropping the Linux platform for Scrivener - it
will only get better and there stills so much more to come on the desktop
and mobile arenas."
