They probably will. MSG will take it because they love money. Forza will put it in as a car pack just like they did for porsche every year till 2017. Or they can go to individual manufacturers and license the cars in that way. I think Toyota and GT have a similar deal for the GR010.
Also that 69B will probably be spent on expanding studios or starting new projects. It absolutely won't be going to FM. If it is going to any forza, then it will be horizon because it has a better return of interest.
Also LeMans celebrating 100 years, forza needing a cover car (probably exclusive and new) makes me think it will be a special edition.
Good thing Ferrari has an LM ready (Its a hybrid too! Absolutely matches the lower emissions thing that xbox is pushing):

Which coincidentally is launching in a month starting with 'J' and ending with 'une'.
