You can call Ubisoft a lot of things but they must have a very big market research division.
They most likely played with about a 100 different names before choosing the one they have.
Even Oleg said he was not happy with SOW. I would however be interested to know what the engine will be called?
You will most likely find that the 'IL2 Surmovik' brand is carried through to the rest of the expansions (DLC) 'IL2 Stormovik Battle for Malta'
