Here's what I think is going on.
If you go over to this site, it would seem that Classic Media is indeed the potential purchaser. However, they will not be purchasing the entire Yugioh franchise (more on that later).
As I mentioned in my earlier post, 4Kids only owns the patent on Yugioh, not the franchise itself. Based on the amortization process, combined with how in revenues it has generated over the past few years, among other factors. I'd say that Yugioh's patent is worth well over $20 million as we speak. I doubt any company (especially Classic Media) would pay that much up front, unless they knew of a surefire way to generate greater revenue s with the limited time they would own the patent.
That said, Classic Media is called what it is for a reason. It's interested in, well, 'classic media.' My guess is that they are indeed interested in Yugioh. What I believe they're after,are the distribution rights to Duel Monsters. That's the only portion of the Yugioh franchise that could actually be considered "classic media. I think what may eventually come out the talks between 4Kids and CM is a revenue sharing agreement (most likely 50/50). On top of that, CM may be obligated to pay an initial fee somewhere around 3 to 4 million.
Beyond that, it would seem that virtually everything on Toonzai is 'classic media.' I wouldn't be surprised if CM is interested in other 4Kids license, such as Sonic X for example, or Cubix,or even 4Kids own produced WMAC Masters, which believe it or not, predates even the days of Pokemon.
Having said all that, 4Kids will continue to retain full control over Zexal. When you combine their mentality that everything they hold the license to has to be created 'their way,' and the fact that they've already dubbed the first two dozen episodes, that pretty much spells it out right there.
