Confirmed.
Surely it’d be fairly safe to presume that Nine News everywhere (both metro & regional) will get the new graphics on Sunday/Monday night.
The only one I’m not really sure will switch over to the new look is NBN News (their equipment appears to struggle with elements of the current graphics), but then again NEC seems to largely let them run their own race to some extent.
Can you get a much better source of info for a relaunch than one of the presenters?
