The availability of FreeBSD 9.0 BETA1 has now been confirmed by Ken Smith: FreeBSD 9.0-BETA1 Available:
The first BETA build of the 9.0-RELEASE release cycle is now available. Since this will be the first release on a brand new branch I’ll cross-post the announcements on both -current and -stable. But just so you know most of the developers active in head pay more attention to the -current mailing list. If you notice problems you can report them through the normal Gnats PR system or on the -current mailing list.
The 9.0-RELEASE cycle will be tracked here: http://wiki.freebsd.org/Releng/9.0TODO
You can download the i386 image from here and the AMD64 is available here.
Since the PC-BSD project closely follows the FreeBSD release schedule, PC-BSD 9.0 BETA1 is available too: Release Announcement: PC-BSD 9.0-BETA1.
The PC-BSD team is pleased to announce the availability of the first beta release in the new9.x series. 9.0-BETA1 is now available for download from the website or ftp server.
