...should definitely have its own thread, as it's certain that there will be a sizable amount of information coming back to this forum from this coming weekend and this will be a nice way to archive the event.
It's worth mentioning where certain large communities on the internet have decided to play (as copied from a Reddit post):
BG's Selected World: Ehmry Bay
Individuals (15): Dragir, Dranio, Eanae, Elrina, Evilmanta, Galion, Iceflare, Imitarate, Iraphine, Killer, Kwijiboe, Purrrfect, Qalbert, Ryoreh, Virtus
Guilds (1): Catalyst (FFXI Server: Fairy), The Star Onions [as 'guests?'] (FFXIV Server: Lindblum)
Note that some guilds belonging to members of BG have decided on other worlds, but there's still time to change their minds! :O

I plan to avoid the more highly-occupied worlds regardless of any reason not to. Ehmry Bay catches my eye (for having nothing in particular attached to it, so it should get little attention), and I haven't read anything anywhere about any large communities using it (yet), but I'm keeping my eyes open. Wherever I wind up, I'll have approximately 5-6 other former FFXI players with me at minimum, I'm sure.
Where is everyone else planning to go? Does BG already have a server in mind? I know some of you have already created your own guilds for the game. Share your plans so we can all get together and be one of the aforementioned annoying, large communities.
