If you want to be ready to mingle into the merry halls of the Manderville Gold Saucer when the Final Fantasy XIV: A Realm Reborn servers will go live at 2 AM PST, you better get that bandwidth ready, because the patch is now ready for download on PS4, PS3 and PC

It's also rather weighty. You'll have to download 1360.10 megabytes on PC and 1140.19 on PS4.

The new patch includes a lot of new content, mostly focused on the Manderville Gold Saucer, including Triple Triad and an exceptionally deep Chocobo Racing feature that will let you breed and customize your chocobo. It'll also let players get equipped earlier in sight of the Heavensward expansion, by adding the option to receive Carbontwine from the Crystal Tower weekly quest, in order to upgrade Ironworks armor.

You can find the lenghty patch notes here.
