From the reliable leaker Seele, it has been almost confirmed that we are going to see two new upcoming characters in Wuthering Waves version 2.6. Both of them are super hyped characters, and you could most likely guess which one they are if you finished the Septimond main story quests.
Wuthering Waves 2.6 Banners

1st half - 5 ⭐ Augusta + Filler limited 5 star character
2nd - 5 ⭐ Luno + Filler limited 5 star character
Augusta is one of the most hyped characters currently, and even leaks of her skills are out on YouTube; she has bold animations and even two burst animations. Augusta is rumored to be an Electro damage dealer that focuses on dealing heavy attack damage. We can expect her to be a new meta-character. Also, she uses a broad blade, and specifics about her forte are not confirmed yet, but you can expect her to be an on-field carry dps.

Iuno is also a 5-star unit, but she takes a different role. She’s an Aero user wielding gauntlets, an uncommon weapon choice that suggests fast, close-range combos. Some leak sources hint at supportive capabilities, including potential healing or buffing mechanics. She is also hinted to be a core support character for Cartethiya’s teams and Augusta's teams.

While the exact 2.6 phase schedule hasn’t been officially announced, the leaked information consistently pairs Augusta and Iuno as the two main banner stars for the patch. And you can expect the release data for Wuthering Waves 2.6 to be on:
