I don't think it's profitable but i think they reduce the lose by a lot in the recent years.
Isn't the 4 billions lose news is about 5 years ago?
PS4 - over 100 millions let's say 120m
Xbox One - 70m
Wii U - 25m
Vita - 15m if it will not get Final Fantasy Kingdoms Heart and Monster Hunter 20m otherwise
3DS - 80m
