An ominous-looking postcard from Marvel arrived today at the Comic Book Resources offices teasing "It's coming." What It might be is anyone's guess, but the note on the back from Editor-in-Chief Axel Alonso promises we'll find out more Oct. 15 at the "Cup O' Joe" panel at New York Comic-Con.

Comic Book Resources will, of course, be covering the entire four-day convention, which kicks off Oct. 13 at the Jacob Javits Center. Marvel also encourages those who can't attend to catch the announcement live at 5 p.m. ET Oct. 15 at Marvel.com/itscoming. "Because trust me," Alonso writes, "you won't want to miss this."
