SoW:BoB?

[Chivas]

BOB's first possible release date was announced by Oleg for the end of 2005, but realized the IL-2 engine would have to be replaced.

BOB SOW with the new game engine was announced by UBI in May 2006 with a release date of Nov 2006. ( We haven't heard anything from UBI since.)

The developer and publisher must have figured that BOB SOW wasn't possible on 2006 computer systems, but there was still money to be made on IL-2 engine addons. So they concentrated most of the developers crew on addons like Pacific Fighters, Pe-2, IL-2 1946 etc. With only one or two people working on the SOW in that time.

Work on SOW began in earnest in 2007 after the release of IL-2 1946.

Many people mistakenly believe that the game is only 60% finished. Its the game features that are only 60% finished. I would imagine the game engine is mostly done as are a very large percentage of the planes and objects.
