Marvel's April 2014 Solicitations bring a number of notable comics to the table -- not the least of which is Dan Slott's upcoming "Amazing Spider-Man" relaunch -- but there are two significant unannounced books coming in April -- a "What If? Age of Ultron" five-issue miniseries by Joe Keatinge and five different artists; and a "Daredevil" #1.5 flash-forward issue by Mark Waid and Javier Rodriguez that teases the state of Daredevil's future in 2014.

"What If? Age of Ultron" follows in the tradition of a "What If?" series for recent Marvel events, including "Avengers Vs. X-Men," "Secret Invasion" and "Civil War" with a look at what the Marvel Universe would have been like without some of the key Avengers. Every issue takes one of the Avengers off the table from the past, exploring what the Marvel U would look like without them "It's A Wonderful Life"-style. Each issue of the five-part mini is illustrated by a different artist, a roster that includes Raffaele Ienco, Ramon Villalobos, Mico Suayan, Piotr Kowalski and Ming Doyle.

Meanwhile, Waid & Rodriguez's "Daredevil" #1.5 serves as a 50th anniversary issue for the Man Without Fear in a one-shot story that flashes forward to Matt Murdock's 50th birthday peppered with clues about what to expect for the 2014 run of "Daredevil."

Check out the solicitations and covers for DD #1.5 and "What If? Age of Ultron" below and the full text and images for Marvel's April solicits here.
