Lego cut off its links with McDonalds a long time ago
Lego as the top toy company has high standards and will not sell its quality toys in massive bulk to lowly fast-food branches that honestly have been just selling cr*p toys lately.They only did it back then because they were dying financially and were in a state of utter desperation.
Seeing Lego products outside of Lego itself and popular retail markets like Walmart, Target, etc. will never happen at this time in Lego's life.
Would likely come off as a Roodaka revamp or something.
