Ok I'll bite. Here's what I think happened:
Oleg/IC had a contract with UBI to produce x sims over a number of years. BOB/SOW development started way before 2007 but the scope changed/increased and rather than abandon that series with UBI at the end of the contract which was approaching, Oleg decided to 'save' BOB for until after his contract with UBI expired. I think this is why we hear Oleg say that development on BOB didn't start until 2007 even though people saw and played demos before then. My feeling is that there is some dispute with UBI about this and SOW won't see the light of day until that's resolved.
Of course I don't have anything to back this up except my hunch. Hey, everyone here has a theory so why not me?
