The "All-New Marvel NOW!" actually begins Dec. 24 with Avengers #24.NOW and the campaign will continue through April with story arcs in ongoing series before the launch of some brand new titles, including All-New Invaders and Inhuman, in January.

"They answered America's call, went to war against the Nazi menace and fought side by side. These guys were brothers-in-arms. As they move into more modern dramas, that link is a link you just can't undo. That will hopefully be the visceral element of this books' identity that will set it apart from the Avengers and X-Men."
