When will ADD support HDs >2Tb ??

In these days where HD sizes are growing and 3-4 TB is becoming "normal" and the first 5-6 Tb disks are coming onto the marketplace, when will ADD get a build or version update to start supporting this, both from the installed version and from the bootable media???
(note that ATI doesn't support disks >2TB from bootable media, probably a limitation from Linux)
