I'm going to quote a whole bunch of things that we'll find out in HOA. I found all this while looking for the bit about the magic systems changing a lot at the end of the book (which I still haven't found yet, funny enough; anyone have that quote?). It's all in blog posts and annotations.
We'll find out which power the Lord Ruler touched.
From Final Empire, Chapter 34 part 2
In the mythology of this world, there are two forced--Ruin and Preservation--and he [TLR] really only touched one of the two powers. But, then, we'll have more on that in later books.
Snapping becomes important.
Well of Ascension, Chapter 34 (funny coincidence...)
Here I also mention Snapping here for the first time in this book. It's an important world element that, unfortunately, I think a lot of people tend to forget.
It doesn't really matter until book three, however, so I'm willing to let it slide in this book, giving only occasional reminders.
Two things; flaring too much is
bad, and something important about Reen...
Final Empire, ch. 7 part 2
Kelsier's warning about not flaring metals too much is a foreshadowing for book three of the trilogy. You'll see what I mean in a couple of years. Also, there's something very important about Vin's brother that will be hard to pick out, but has been foreshadowed since the first book. . . .
Why did the Koloss divert to that village (don't remember the name; lent out the book)?
WOA, ch. 37
In book three, you'll be given a reason why the koloss diverted to the small village mentioned here before going on to Luthadel.
Mists get pushed away by Hemalurgy. Why comes in Book 3
Final Empire, ch 38 part 2
By the way, the mists getting pushed away from Vin and Kar here is a clue of some sorts. Inquisitors push away the mists, rather than attracting them, when they use their powers. I'll explain this in book three too.
Flowers! Why there aren't any, and how the world still works!
Final Empire, Chapter 17 part 2
Flowers. It was actually hard to write a world without flowers. For instance, the scene where Kelsier fights in the conservatory--I had to struggle to not call things flowerbeds. Describing gardens without flowers was tough too.
So, how does a world get by without flowers? Why don't they exist any more? All these questions will be answered.
In book three. Sorry.
More about Koloss
WOA Ch 42
The koloss are meant to be creepy. Their line about taking the city, then living in it isn't just a random comment--we'll get into this a lot more later on. (Particularly in Book Three.)
Kandra Religion
WOA 33
There is a kandra religion. I'm not going to be able to talk about it until book three, however. The things OreSeur is talking about here aren't really fundamental aspects of it, however. More. . .lore associated with the religion than actual tenets of that religion.
Why "Hero of Ages" and not Final Hero?
WOA Title Page
I quickly decided that I liked Hero of Ages instead of Final Hero (you'll see why in Book Three.)
Who pewter drags the continent? We can assume El, but for all we know it could be Marsh, or someone else.
Final Empire 25 part 1
In book three, I have one character crossing half the continent, then having to run back the other way, just so he can get where he needs to be for the end of the book.
Wells has another cameo in HOA (perhaps not important, but who knows?)
WOA 43
Oh, and the guy on the wall--Wells-is a cameo. He is my good friend, Dan Wells. He's not this much of a coward, but he didn't make it into book one, so I figured I'd throw him in here. He'll be back, actually. . . . (Watch for him in Book Three.)
Where the legends of the 11th metal came from
Final Empire 27 (hidden spoiler)
The answer is, by the way, yes. He did find those legends--legends that Sazed hasn't heard of. Legends nobody else has heard of. That is suspicious, true, but Kelsier himself believed them. More on where he got them comes later in the series.
And, of course, we'll find out about the 11 spikes and Hemalurgy in general as I mentioned a couple of posts ago.
I know one thing; we should find out why Inquisitors have 11 spikes:

Swiffy writes, "Is there a significance to eleven spikes [in an Inquisitor's body], or was it just a convenient number?
My Answer: Yes, there is a significance to the number. Good catch! You'll get more in future books. I can't explain it now, however, because it's something of a spoiler!
I can say this. Each of the three Mistborn books deals with one of the magic systems. In book one, the focus was on Allomancy. That same amount is there in book two, but we also add Sazed as a viewpoint character and begin talking about Feruchemy. In book three, we add an Inquisitor as a viewpoint character, and begin talking about Hemalurgy--the magic that keeps the Inquisitors alive and gives them their powers.
That's what I've found so far; I think we're set to find out a lot in around 10 days.
