Off My Mind: What Will The End Of Brightest Day Bring?

These days, comic book events tend to flow from one to the next. Some have been self contained and others involve most of the comic universe. With the end of Brightest Day fast approaching, I started thinking how much has changed since the start? Has there been any payout from this event? 
 
Comparing Brightest Day to Blackest Night, even though we had a lot of miniseries tie ins for Blackest Night, it almost felt more self contained. Brightest Day has not only been a bi-monthly series but also a brand on several titles like Green Arrow and Green Lantern. The story itself involved many of the twelve that were resurrected at the end of Blackest Night. This gave the series a broader feel but also made it harder to follow along with multiple storylines fighting for space in each issue. We only had pieces of the story and some characters' went untouched for issues at a time. 
 
With the image of Deadman released earlier this week, it doesn't look like everyone will have a happy ending, despite the overall mood being lighter. Deadman has returned to life and has been having a pretty good time eating cheeseburgers, getting close to Dawn Granger and getting reacquainted with his relatives. But what does this image mean? 
 == TEASER == 
The pile of dust could be a number of things. My first thought was because he is getting closer to Dawn, maybe she somehow gets blasted into dust. I don't think that will be the case as she has another fate in store (more on that in a second). Most likely something will happen to the actual White Lantern power battery. Deadman was supposed to find the new guardian for life but what if he fails? It could be that he made a choice that burned out the Lantern. If that's the case, what does that mean for the lives of those that were given the chance to return from the dead? Can they still have life if the force that brought them back is destroyed? 
 
What about the other prophecies the Lantern told the others?  

Captain Boomerang has to try to kill Dove. Jade needs to help her brother balance the darkness (which we'll see in upcoming issues of Justice League of America). Osiris is still unable to free his sister. The idea of Max Lord trying to stop a war doesn't seem to likely as he's focused on finding Wonder Woman. Hank Hall has to save Dove. Professor Zoom seems to have already accomplished his task. 
 
This brings another question, what if any of these individuals fail to accomplish the task bestowed upon them? Was this part of the deal in getting a second life? I've always questioned why the Lantern would want Boomerang to try to kill Dove and Hank to save her. All it would accomplish is making sure Boomerang stays true to his evil ways and for Hank to make sure he can be a hero. The Lantern is supposed to be a force for Life yet bringing back a killer goes against the idea. 

I always felt that the return of these twelve would pave the way for more comic series. How long until we get a Firestorm, Deadman, Aquaman or Hawkman & Hawkgirl comic? Going back to the first image, I don't think Brightest Day will end on a completely happy note. I see something really big and really bad happening. I don't think Deadman will stay alive. More importantly, I want to see what happens if one of the twelve fails to accomplish what they were told to do. Will the fate of the White Lantern have any part in the upcoming War of the Green Lanterns?
