There were a couple of clues at the end. Some of the new foods can be seen sitting alongside a lot of the existing ones. And at least one new building piece also appeared in the same scene with the wooden brackets surrounding the fireplace, carved into a woven pattern. We know that these are new content as they have been shown in in-game screenshots previously.

It is a bit of a weird one because there is not a clear divide between new gameplay elements and things that are simply artistic license. Despite revealing the date for an update focused on home activities, hardly any of it was at home.

I do agree though. After the roadmap collapsed, teasing this hard doesn't seem quite fair. Collectively they haven't let us in on a lot of new content and I worry that they've been stretching it out because there isn't actually much to show. If that turns out to be the case it will greatly influence my expectations when it comes to further updates/teasing.
