Interesting. We can guess a few things about the timeline from what little we've been told. Here's the translated table of contents:
History of Hyrule
~Finally Revealed, The Genealogy of the [Legend]~
The Timeline of Hyrule, Kingdom of the Gods………………………………..68
The Legend of Gods and the Hero of Time…………………………………….70
The Downfall of Hyrule and the last Hero………………………………………..92
The Twilight Realm and the Hero’s Descendant…………………………… 110
The Hero of Wind and the new World……………………………………………..122
The first section is only two pages. Probably just the back-story and stuff we already know. Most likely, this will just clear up a few of the dubious retcons. The remaining four sections will cover the games themselves, I'm guessing.
Important to note is the fact that the first section is the longest, as far as we know; yet the only games we know are there are "Skyward Sword" and "Ocarina of Time" (possibly "Majora's Mask"). This could mean that there are a few other games that will be covered in this section. How many? No more than three, I'd presume.
The third section is fairly short and might just contain backstory. However, it might contain a game or two as well. This means that some games might go between OoT and "Wind Waker", or OoT and "Twilight Princess".
The fourth section clearly covers TP and a few other titles. Most suspect that "Link to the Past" will be here. "Oracle of Ages" and "Oracle of Seasons" will most likely be here as well.
We don't know how long the last section will be, but its quite clear that it covers WW, "Phantom Hourglass", and "Spirit Tracks".
I am looking forward to reading it.
