i am really confused about this.. remember what Jean told Emma before that "Visions come to prepared spirits.."? i have always thought that it meant that Jean Grey was about to be resurrected soon..   
 

i completely read that all wrong in x-men. thought it was just madelyn messing with her brain housing. good eye. good ideas.

I believe that something crazy is gonna happen which may lead to her returning, though Jean isn't finished collecting all of the pieces of the Phoenix Force yet, until then she has yet to return, though i'm sure it should be soon.

Hmmm...can't say that I know what it means myself...it's a bit cryptic...I would assume it has something to do with her return and her passing on visions of the future to Emma...maybe visions of her return to the X-men...maybe the visions were something to do with Hope...

Love the OP and me thinks it means either Jean Grey is coming back or the something really big is coming concerning the phoenix force itself

I can dig it.

she references the phrase "visions come to prepared spirits." i think people are over looking the visions part. i think she is telling emma to prepare for visions. idk. i doubt the writers have thought this much about it.

It's kind of annoying, I'm all for foreshadowing or at least hints to future storylines but when the hints go unanswered or not called to (not counting the above mentioned second coming hint) for months almost years is when they need to hurry up and do it or let it go. But since I have no say I guess i'll throw my guess in I think the Little Spirit phrase calls to Emma taking hold of the Phoenix, Jean was preparing Emma for that power, they've always hinted at Emma getting TK powers and now with her being the prominent Telepath i think they're building on it especially with her former students recently having it and one of those Phoenix songs hinting to it at the end, Maybe even ressurecting Jean or doing a little Rogue/Ms. Marvel dual psyche thing.

there are hints of who will be the key in defeating Mikaboshi.. this is from an interview with Pak and Van Lente on Chaos War #3..  

Nrama: "Last thing before you guys go — any further hints or anything you want to tease about Chaos War #4?"

Van Lente: "A “cosmic”/mythological entity that is very important, and has been very important in the Marvel Universe, plays a very prominent role in this issue, although we have not seen her — yes, her — yet in Chaos War.." 

 
who is "she"? who is this light of hope that will ultimately drive of the darkness and chaos? i'm still won't be naming names just yet.. let's just wait.. 
 
by the way, here is the complete interview.. http://www.newsarama.com/comics/chaos-war-from-the-field-4-101112.html      
 
 
maybe these scans can help.. 
 

i also remember Jean words before she was killed by Xorneto (Magneto)..  
 

"This is what it means to be the Phoenix... to keep coming back, to be the last hope, winning against all the odds."   

What comic is the Emma Frost/Jean Grey encounter in?

which one. the above one is from uncanny x-men sisterhood
