Well I know they wouldn't be putting the movie in a bunch of people's faces, but they would still acknowledge it every now and again, like how they would maybe post a twitter message that was Zootopia themed like they do randomly each week. Or they would say something about it here and there, since it won a Oscar, the highest award a movie could win, but still they haven't said a word or done anything that hints at Zootopia online or whatnot (outside of Disney Parks) since the sue...
Honestly, they even acknowledged Wreck-It Ralph from time to time after it became an old movie, but still there is nothing to hint at Zootopia since the sue.
But I am sure this suing thing is going to end soon enough, and if Disney does come out victorious, then I probably see Zootopia being in the next chapter of Kingdom Hearts after KH3. I don't think they would want to put it in KH3 cause KH3 would still be too fresh on people's minds and Disney would probably not want people to think about the case. However, by the time KH4 comes out, I am pretty sure the time would be right to add in Zootopia to the mix.
