I do seem to remember someone mentioning that if the wardrobes have disappeared from the seat map in MMB it means it's NF, but I might be wrong, so hopefully someone else can confirm yes or no.

In regards to NF you can always call YouFirst 24 hours before the flight to find out if it is or not, although judging by the answers to the question I asked in relation to this in the NF thread it's not always reliable even a few hours before the flight...
