yeah, it looks like it's a timeline of hyrule only, and maybe not all games will be listed.
Like Castlevania, they officially "removed" and "merged" a lot of games to make it a more consistent timeline.
based on the chapter's titles, it's just big timeline which looks like :
The Timeline of Hyrule, Kingdom of the Gods………………………………Skyward Swords
The Legend of Gods and the Hero of Time……………………………………Ocarina of time
The Downfall of Hyrule and the Last Hero………………………………………?? (Zelda2? link to the past? all others?)
The Twilight Realm and the Hero’s Descendant……………………………Twilight princess
The Hero of Wind and the New World……………………………………………Wind Waker (and spin-off), Link's awakening (awakening to what? he just dreamed he was a hero in past lives, so will he became one too?)
Well, We will see what they have decided to change to make it a consistent timeline. They have many choices to pick from many players who made a timeline long ago
