I don't buy the Flash thing. I can't see that. He's too young. As for the downloading of comics. I've partaken from that well. There's a series I'm contemplating getting into? I'll download a few issues and see if I like it before making it a monthly book.
If the Flash thing is true, it better well be temporary (like the Batman one). Just for the One Year Later thing for a little while. My bets for a permanent change are still on WW. I used to download comics, but I got so far behind in reading I just gave up on those. If I can't find the time to read something I got for free then it's probably just not worth it. I still buy all the books I actually want to read.
I hope the Flash thing isn't true. I don't read Flash, and know very little about Wally West, really. Still, considering what happened to the Flash back in Crisis on Infinite Earths, it looks like DC is going to be starting a running trend (no pun intended on "running"). Of course, this means that 20 years from now... watch out, Bart. And yet Jay Garrick continues to outlive them all.
Johns might've done some foreshadowing in some comics he worked on, like in the Titans/Legion crossover, where Bart's mom remarks something like, "There goes my son, The Flash." There was also the Titans encounter with the future versions of themselves (where they mentioned that a lot of heroes disappeared--Maybe that's what happened to Wally?).
