I will argue that pretty much ALL of those Disney rides either:
A.) Got updated with more relevant IPs.
B.) Have gotten new material like with the live-action movies, TV shows, merch, etc.
Even with something like the Harry Potter land at Universal, the series has still gotten merchandise, some spin-off movies, a Broadway show, and an upcoming TV series.
How does this relate back to DK at Universal? Nintendo will need to start making merchandise with characters besides from Donkey and Diddy. However, the important thing is that they need to do stuff like with movies and games. Isn't the whole point of Nintendo becoming an entertainment company is that their other businesses help them sell the games? If there is a Donkey Kong land and movie that's coming in our way and yet, no new game comes out soonish, then it would be a bad business move on their part.
