During the Planet Hulk panel tonight, Marvel Editor-In-Chief Joe Quesada was asked about the cosmic line of comics.
His response was: "In publishing, we talk about Marvel Cosmic a lot right now. Generally what happens in publishing goes out into the rest of the business. Expect a lot more Marvel Cosmic in other aspects of the business in the next 2-5 years".
Sounds promising for an Annihilation or Nova movie of some sort in the future!...or maybe that's my wishful thinking. :)
