I wouldn't believe it until I saw it, but now I've seen it, and now I believe it. On the Kingdom Hearts Ultimania site, they have pictures and magazine scans of the Tron world. My apologies to dejavu, even though he/she is banned.
I kind of like how they are giving Sora and the gang various outfits to fit the world, it's kind of neat. Anyway, here's another world for your viewing pleasure. The heartless for this world should be interesting. Discuss.
