Of the Animated features coming up, the only one that has a chance is Toy Story 4. Outside of that, maybe Incredibles 2, but I doubt it.
Realistically, I think we're still 4/5 years, at least, away from that. It took 12 years to beat Shrek 2, which took 10 years to beat Lion King. Though now that I think about it, If one were to define the Lion King remake as solely animation, that has the best chance in the near future.
