It'd be a really nice bit of goodwill from Microsoft* to allow
Goldeneye to appear (especially as they make a statement every week saying that the Wii's a failure, so what harm would it do to 360 business?), but "goodwill" and "Microsoft" don't tend to go together.
*Obviously, it's not just MS who stand in the way. EA own the Bond licence right now, but even if all the Bond references were stripped out, it's still a Rare/MS game.
