The devs have indicated that Dreamlinux 4.0 beta could be out sometime in late spring or early summer. The forum community has polls available to give the team an indication of the direction that they would like to see the distro take.
If you are a Dreamlinux forum member, I encourage you to take the poll at Dreamlinuxforums.org
and make your voice heard. Look for it in the news and announcements sub-forum.
