It happened yesterday. Check out the Dark Worlds Magazine blog if you don't believe me.
What will it mean? Spiderman will show up in the Disney Christmas Parade. The Jonas Brothers will have a song on the Wolverine 2 soundtrack. The theme song for Iron Man 2 will be sung by Hannah Montana. The saturday morning cartoons based on Marvel characters will get better animation. Other than that it will be business as usual.
That and my daughter, who owns shares in Disney, just got richer. She now owns a piece of the Marvel Pie. Cha ching!
