I think DC is going to kill/remove Bart and bring back Wally to be the Flash. . .this is why they are hinting something big is happening in the next few months. . .I think they finally realize the Bart experiment as the Flash is not working and we all want Wally back; mark my words--Bart is a goner!
Over at Comic Bloc, Marc Guggenheim explicitly said they were not bringing Wally West or Barry Allen back as the Flash and Bart WAS the Flash for the future, in fact he actually shared with us a line of dialogue from issue 13 spoken by Bart: "I...Am...The Flash!"
