For the menus, I did a double take myself given how recently this was changed. I've seen a picture of these new-new ones and they are indeed different than the regular "new" ones that started circulating a few months ago and are ubiquitous in J class now. The new new ones are more like menu cards than booklets.

While i am certain about it rolling out on CX846, I am not sure if there will be any change to CX845 (or any of the other ex-US flights). My GUESS is no, because there are a lot of catering and product changes to the entire meal service that presumably are only being tested and perhaps on a limited basis. So I think that would be CX Catering Services only. I also am not privvy to whether or not this is going to other USA destinations or just CX846 for the time being, and when it will be rolled out further.
