Yes, it's a really good move on their part, and achieved through some  
clever legal work. CC-BY-SA is much more explicit and unambiguous for  
their purposes (the GFDL article on Wikipedia shows some of the  
criticisms that Wikipedians have of their current licence), just as a  
data-focused licence could be for ours.

It is worth noting that Wikipedia's licence has no effect on whether  
or not Wikipedia can use OSM maps. Wikipedia already admits images  
from a whole host of sources under "free licences", even with licences  
as obscure as "Trainweb" and "Ubisoft-screenshot" (!); if Wikipedia  
does move to CC-BY-SA, the Collective Work provision will would  
continue that. No licence OSM would ever consider moving to would be  
outwith Wikipedia's definition of a free licence - OSMers simply  
wouldn't agree to that!
