What Little Niggling Details will be left?

I can't remember the last time this happened, but I'm actually using 
up my 5th post of the day.  I must be getting excited about the 
release or something. :)

Anyway, I've just been chatting with someone offlist and got to 
wondering about something....  

Quite some time ago, "The List" was put together and posted in the 
Essay section over at the Lexicon.  This is a list of all the things 
that some folks (notably Pippin, AKH and Serenadust) had come up with 
as Items Which Still Needed to Be Answered by JKR.  (To peruse this 
list, go to:  http://www.hp-lexicon.org/essays/essay-the-list.html )

So I got to wondering about this:  Just what do you all believe will 
go UNANSWERED from among those things which are driving you nuts?  
These could be Big Mysteries, of course, but I'm thinking especially 
of those Little Niggling Details.  I mean, not SO little niggling 
things, like "What color socks does Dumbles favor?" but perhaps 
slightly more significant little niggles such as get debated here 
amongst those of us who consider ourselves "major fans."

Here's an example of something I've just decided is likely to go 
unanswered:  The question of just how much Snape heard of the 
prophecy at the Hog's Head.  

We argue and debate whether DD's account of things is accurate (that 
Snape heard only the first portion of the prophecy before being 
tossed on his ear by Aberforth), whether Trelawney's version is 
accurate (that Snape was still there when she *finished* the 
prophecy), or perhaps even that there's a third option -- that DD 
*thinks* Snape only heard the first part but perhaps Trelawney is 
correct and he heard it all (and if that's the case, perhaps he 
*chose* to tell Voldy only the first portion?).

As much as I'd like to know which of these is accurate, I seriously 
doubt JKR is going to revisit this.

So what say ye?  What Little Niggling Details do you fear will be 
left unanswered at the end?
