I'm not exactly sure where to look, im trying to figure out when the update with the new killer is.
The best place to look is the "News" category. That's where all official announcements get posted. https://forum.deadbydaylight.com/en/categories/news
If you're not on mobile, there's also a Twitter feed at the bottom of the sidebar where all the latest tweets from the Dead By Daylight team appear (although usually any important information that they tweet will also be shared in a banner at the top of the forums).
If you're looking specifically for the release date of the next chapter, it's been officially confirmed that it will release on December 3rd. Based on past patterns, the release will most likely happen at 11am ET (10.5 hours from now) or soon thereafter depending on which platform you're on.
They usually aim to release updates at the same time on all platforms. There may be a slight delay on console due to verification processes the patch has to go through, but it shouldn't be more than an hour or so and most of the time it's only about ten minutes, if that.
is that pc only for the update or console too?
And you could check the patch notes section
