http://www.animenewsnetwork.com/news/2011-05-17/4kids-files-to-prevent-yu-gi-oh-zexal-licensing As suspected, we have to wait until the court's decision before learning the fate of the 5D's and the ZEXAL dub.
NAS/TV Tokyo were looking for another licensor as to how they were going to exhibit ZEXAL at that Licensing Expo in Vegas. (it's a good thing that they and 4kids have booths pretty far away lol, can you imagine if the NAS booth was right across from 4kids, with funimation a little ways down? Epic glaring contests much? lol)
Even if 4kids is found "not guilty" their reputation, especially history with the yugioh franchise makes me think that ZEXAL is honestly the best time for 4kids to stop dubbing "yugioh"
Granted if it wasn't for 4kids, I wouldn't have been introduced to Yugioh (or pokemon for that matter as to how I didn't have a game boy or video games back then) but considering how they dubbed and DIDN'T FINISH GX, the overly (sometimes ridiculous) censorship of the 5D's dub (though granted, I very much enjoy the 4kids' VA's talent and acting skills, and I commend them on that, also it's gotten... better but it's still unnecessary) I would really like to see ZEXAL dubbed by someone else.
It's good timing since ZEXAL doesn't (so far) have relations with DM, GX, or 5D's thus could have an entire new VA cast, etc (and no offense, he's a great actor but...) without Dan Green popping in every 4 characters or so to confuse those who don't look at the show to think Yami Yugi reappeared. But then we wouldn't have those 4Kids yugioh Openings for ZEXAL :

Sadly it seems the court hearing is May 31st, and this may mean given a few months if 4kids is found guilty, the 5D's dub would end production... (and I wanted to see Aporia (probably would be renamed "Adam" or something... I'd think Antinomy would be renamed "Anthony"... ... ... PLEASE DON'T DO THAT 4KIDS)
