Around December 9 (late 1.1)

1. Content-wise the Chasm should be similar to Dragonspine, festival events similar to the 1.1 event which has three stages with stories.
2. Hu Tao's e gives her pyro enchantment at the expense of constant hp loss, the less hp she has the higher damage she deals; she also comes with a red spear, sub stat crit dmg, +20% hp bonus and +1% atk per 1% hp loss. He only saw a screenshot of that, not sure if the current design would make it out of the test server.
3. Xiao comes first in 1.3 then Hu tao; Lantern Festival has gameplay similar to tower defense.
4. Wind Flower Festival (Valentine's day) in 1.4, Rosaria is the only known new 4 stars for 1.4 so far, second banner is Venti rerun but he's not sure what would be the 5* pickup for Rosaria's banner.
5. Release schedule up to 1.4 is already set in stone, for 1.6-1.8 it's not yet decided if Feather Ball Festival or Inazuma comes first. Klee banner rerun should come with Feather Ball Festival, Inazuma could come in 1.6 at the earliest, starting from 1.5 there will be new characters that are not leaked yet. The housing system is scheduled to release before Inazuma. Currently no plans to add Signora and Scaramouche into banners.
6. The datamined character "Kate" is just for background testing (Honey said so as well) so won't be released. He also denied the popular theory that Shenhe is the crane adeptus from Liyue (cryo claymore female character whose costume looks like crane)
7. Sumeru's (the dendro nation) setting is that people who die in the day would be revived.  Inazuma story spoiler the player would find out later the real electro archon is already dead, the current one is just a puppet, everything is a hoax to pick the next archon, Ayaka is one of the candidates. Since the end of Liyue main story is now different from what he saw before, this might get changed as well.
8. At launch there were no plans for events based on irl festivals cuz they wanted to control how many resources players get, the "no mid-autumn festival & National Day" backlash caught them off guard, they have made xmas themed artworks beforehand and wanted to release those only for global servers, but came to realize this would probably bring further backlash now that they've already made the "no irl festival events for genshin" excuse.
