Marvel Comics has continued to unveil hints at new Marvel NOW! arcs in April, in the third day of such teases (see "New Marvel NOW! Arcs"). 
First, writers Gerry Duggan and Brian Posehn unite with artist Mike Hawthorne on Deadpool, with the tease “I Scream.” Duggan and Posehn oversaw the relaunch of Deadpool in late 2012 with artist Tony Moore. 

More mysterious, however, is the purple-clad, single-word tease for something by Jason Aaron and artist Simone Bianch, teased with “Birth.” 
Both the new arc of Deadpool and the mystery title are scheduled for an April 2013 release.
