We're still waiting for the FDL 1.3. Since there's been no resolution within the timeframe we hoped for, we're going to re-allow the creation of new Wikimedia wikis. To make sure that we can safely transition to CC-BY-SA, we're going to dual-license them under CC-BY-SA 3.0:
http://creativecommons.org/licenses/by-sa/3.0/legalcode
We may remove this dual-licensing clause later, depending on what the community decides with regard to licensing of existing and new wikis based on the options that the FDL 1.3 will provide. This dual-licensing of new wikis is purely intended to make sure that we have the _option_ to transition these wikis to CC-BY-SA 3.0 (or later) if we choose to.
