Thanks to the Rogues, I think The Flash Blackest Night mini has a bit more "guts" and character to it than the Wonder Woman one, which I really don't think needed to be a mini unto itself (maybe a one-shot?).
At this point, I can easily see The Rogues supporting their own series under the right creative team.
I keep wondering how they are going to be collecting these side miniseries in relation to Green Lantern and the main Blackest Night mini.
Reading them as they come out week to week, one might suspect that collecting the whole shebang chronologically like Seven Soldiers works better than having someone read the Blackest Night collected Edition, followed by The Green Lantern Blackest Night collection, GL Corps BN Collections, Flash BN Collection etc.
