Would that by any chance have anything to do with DC Comics Infinite Crisis? I saw it in the comic shops and book stores.
I also got an e-mail a few months back for a DC MMORPG Video Game of the same name.
I have no IDEA what either of them are about as I didn't buy the comics because, well, I was there only for Batman, The Flash, Wonder Woman and Superman New 52 issues. However, if Infinite Crisis is canon and has something to do with Barry Allen then I'll certainly go back by and pick that Infinite Crisis comic up the next time I am in town.
