Nope. The game is already delisted, so they are not going to sell it again, therefore licensing doesn't apply here. Only if they resell the game would licenses have to be renewed, from my understanding anyway. This would just be a great benefit to owners of Forza 4 and MS can add it to the "X-enhanced" list, in case gamers ask why there hasn't been an x-enhanced game in a long time.
If this turns out to be true, then everyone has to remember to move your save from the 360 to the cloud if you want your save to transfer over. I had to do this with Horizon. Other 360 BC games, I was able to copy the save over, but I guess some games you can't.
