There was a tweet yesterday about pre-load - https://twitter.com/playnewworld/status/1440857004034039809
"You can get yourself ready to #playnewworld by pre-downloading the launch client starting 9/27 at 8 AM PT (11 AM ET)!"
The offical site has announced launch times as well:
8AM CEST EU Servers will launch (9/27 at 11pm PT)
8AM BRT South American Servers will launch (9/28 4am PT)
9PM AEST Australian Servers will launch (9/28 4am PT*)
8AM ET NA East Coast Server will launch (9/28 at 5am PT)
8AM PT NA West Coast Servers will launch
There's potential that EU servers will get swamped as people try and reserve names because some people suggest naming was a global thing although I can't confirm that (It's at least going to be unique for each cluster because of expected server merges which was tested in Closed Beta)
If names are a global thing then that is some of the most insanely naive never played an MMO before in our lives, design right there. If they are global then the first servers to come up will just be absolutely flooded with players from the other times zones trying to secure their names. The names simply must be zonal or even more preferable server based, I mean literally any apprenticeship game designer with any nous at all about MMOs would know that.
