I've gotten an email from delta, about the new chat. and the picture was 4 years ago. it has been worked on for a long time.
I've seen that image too. It makes me scared every time I see it
The chat is having a complete rework and recode ( once all the other bigger projects are out of the way )
so anything you've seen or hear about the chat is likely not going to be in the final result. Although I know for sure that private rooms will be a thing because thats a big focus. Other than that, who knows...
