Good point. I guess the bigger news announced today would be that you can now download a Release Candidate of Lync, too.
UPDATE: Be warned that if you simply want to try the new Lync client, it won’t work well against your existing OCS installation. (Thanks to Jeff Schertz’s Blog for the heads-up.)
