The fate of Flashes, major and minor, was discussed at the New York Comic Con 2009.
First, from Newsarama:
DiDio then brought a fan in a Kid Flash outfit up to the dais to pose for a picture with George Perez. The fan asked about the future of Bart Allen: “He’ll be in the 31st century in Legion of Three Worlds,” said Johns, adding that he’ll be back in the Flash universe as of Flash: Rebirth.
“If Wally West is just going to be in Titans and guest starring in Flash, aren’t you basically making him Kid Flash again?” “Who said those would be the only books he’d be in,” asked Sattler.
“How many Flashes will you kill in Blackest Night?” “Not enough,” said DiDio.
Anything coming up for the Rogues? “Yeah, it’s called Flash: Rebirth.”
Johns gave some hints about Flash: Rebirth. “It starts April 1, April Fool’s Day. It will come out.” The writer talked about the return of Bart Allen, and said the goal is to have fun in the Flash universe in the same way they’re currently having fun with the Green Lantern universe.
Then, from CBR:
Geoff Johns then discussed “The Flash: Rebirth,” which comes out on April 1, confirming that Bart Allen is back and will play a big part in the book.
Where can we see Bart Allen next?
Geoff Johns: He’ll be in “Legion of 3 Worlds” and in “The Flash: Rebirth.”
More Max Mercury? Maybe.
Kid Flash back in “Titans?” “We have to fight about that.”
The Flash Rogues? See “The Flash: Rebirth.”
