When i phoned UBi in the UK, i originally spoke to a receptionist, i asked him if i could speak to someone about the release date of SOW, , he asked what type of game was it because he had not heard of it, i told him its a flight sim. I was then transferred to a guy that had worked with the IL2 series. He knew all about OLeg and Il2 and he had a little knowledge of SOW but insisted that it was nothing to do with Ubi, he then said that i should talk to another guy who was much better informed than himself, he put me through. This guy knew all about 1C and Oleg and about SOW, his words to me were that Ubisoft were no-longer involved with the project. Which when you think about it makes sense, according to Oleg the game should be released within a year, so you would imagine that if Ubisoft were involved they would of already started to get the marketing ball rolling.
It could be that the guys at Ubisoft all told me a pack of lies, it could be that i am telling a pack of lies! However since no-one else has bothered to make a call to check then this is the best info i can give you. It matters little to me anyhow, because it is obvious now that this sim will be released whoever publishers it, but from my info i dont think it will be ubi.
