Quoted from PanzerFreak:
What happens though when the McDonald's burger is smashed when you open it, doesn't look as good as the burgers they once made, and for some reason cost the same amount as the fillet from Capital Grille? Lol. Haste makes waste and for BTTF I much rather wait for JJP to make it with unique toys and deep code that spans all 3 movies.
The REAL problem is if JJP obtained the license, you'd need a flux capacitor so you could travel 4-5 years into the future to finally see it in production.
