Just a quick drop in to give people a heads up on something.
About a monthy ago I stopped into my fiancee's local Toyworld to see if like with other exclusives, Masterpiece Optimus might also be going through them.
They didn't have any pictures but what the manager there said said was that their two big exclusives were going to be Omega Supreme and Optimus Prime and they were going to be over $100. They were also expecting Generations Voyagers so it's possible that these are the asian exclusive Generations figures.
Considering that the only large scale Omega Supreme currently around that would be in that price range is the YOTS, my guess is that that was the Prime and Omega they were referring to. I'll leave it for people here to confirm and clarify and if I get a chance to contact them in the next few weeks, I'll let people know what I find out.
