So next Tuesday our first normal tier of Eden comes out.

The following week the Savage tier of Eden drops as well as the new treasure hunt instance Lyle Ghiahl.

Stormblood came out on June 20th (officially) and we didn't see 4.1 drop until October 10th.

With Shadowbringers coming out on July 2nd It's safe to say at the end of October we'll get our first big patch update.
