Apparently they did lisense it, if you go under anime databases such as animenewsnetwork.com and check it's listed as lisensed by 4Kids Entertainment, so they did lisense it back in 2006 and said they would broadcast it in the fall, but now it's 2007 and we haven't seen anything.
First all, 4Kids entertainment always makes a mess of the anime they lisense. Not to be biased but I have seen many of them and they are really bad. So, it would be messed up.
Now as to if it would ever appear or not, we really can't know untill they make another announcement reguarding what they are doing with it. It's possible they lisensed it and couldn't find a station willing to broadcast it (as this has happened with ADV when they lisensed Mermaid Melody Pichi Pichi Pitch, and they couldn't find anyone willing to broadcast it and in the end they dropped their lisense of it)
It's possible that 4Kids might drop their lisense like ADV, or they are just having it on hiatus and will have it appear sometime later this year or later. But, more than likely, even if they do get it on tv, it will flop. Unfortunatly, shoujo (girls) anime dosen't do well on U.S. TV. it's been proven over and over again look at Escaflowne (taken off broadcast and not finished) Card Captor Sakura (taken off broadcast) Tokyo Mew Mew (taken off broadcast). Companies know they are taking a big risk with shoujo anime, they end up not being as popular as titles such as Naruto and Bleach and because they are edited and numbed down even more to be even more kiddy..it just dosen't go over well.
so, in short my t heory is they rather can't find a broadcaster or are in hiatus deciding if it's going to be lucrative enough or not.
