FYI, pictures and details of the new cabins and services have been "announced" (or should I say "leaked" since JAL has removed the press release from their site now). The new catering service will definitely come to the NRT-ORD and NRT-CGK flights because they are rolling that out in Jan 2013. You will get that even without the new SKY SUITE 777 on those flights. You can find more details on this thread from the JAL forum:

Not much catering info other than they have recruited 4 famous chefs from Japan to be in charge of the menus and some pictures
