It would make "sense" from their perspective to hold out on FO3: If indeed they are unable to make any D&D games after 2005, they would want to bust ass to crank out as many of those as they can because of the brand recoginition. After they can no longer publish D&D games, then they would return to their own franchise, which will always be there for them (to exploit).
