The last copyright extension might be the last Disney could push for. If they pushed it significantly further, they would lose the copyright of their older works to the Brothers Grimm. Walt Disney's first animated film "Snow White and the Seven Dwarfs" was published in 1937, 74 years after the death of Jacob Grimm. The Mickey Mouse copyright extension is 70 years after the death of the longest surviving creator. That said, they could lobby to increase copyright terms for post-1927 works only, or corporate works only and leave natural persons out in the cold. It's uncertain whether these moves would be too politically extreme for Disney.
