Amazon has a listing for The Flash by Grant Morrison & Mark Millar, a hardcover collection coming in April 2016. Morrison and Millar co-wrote one year of Wally West’s series back in 1998-1999, while Mark Waid and Brian Augustyn took time out to do JLA: Year One. Paul Ryan and John Nyberg did the art on the first few stories, with Pop Mhan and Chris Ivy taking over for the final story, “The Black Flash.” Steve Lightle did the covers for the full run.
The timing is undoubtedly related to Morrison’s upcoming Multiversity Too: The Flash OGN.
Back when the softcover collection was announced, this site’s very first news post (after the “Welcome!” article) featured a quick run-down of the contents:
The stories had a much more sci-fi take on the character than had been seen since the Silver Age, and included:
Emergency Stop (#130-132): The Flash finds his own dead body, sent back in time from the future, and has to solve his own murder. Introduced The Suit, the ultimate super-villain costume that came to life, draining those who wore it.
Flash Through the Looking Glass (#133), battling the Mirror Master.
Three of a Kind (#135): Part of a crossover with Green Lantern and Green Arrow, in which the youngest members of the Justice League try to take a vacation…only to find a trio of super-villains is on the same cruise.
The Human Race (#136-138): Wally must compete in a galactic race against his childhood imaginary friend, Krakkl of the planet Kwyzz. If he loses, Earth is destroyed. If he wins, Krakkl’s homeworld is destroyed.
The Black Flash (#139-141): Death comes to everyone, even speedsters… but this time, Death takes the wrong target. Introduced the Black Flash, who featured prominently on the cover of last year’s cover for Flash: The Fastest Man Alive #13 (remember those Dead Flash Covers?).
