Is there a Likelihood of Kingdom Hearts and Star Wars mash-ups?

It was mentioned that fans of Kingdom Hearts could feel confused concerning the recent trailer for Kingdom Heart 4 since they noticed the hint of Star Wars crossover. 

After the official announcement on the 20th anniversary of Kingdom Hearts', the development of Kingdom Heart 4 is in process. Fans started proposing hypotheses about another world appearance possibility in a crossover between Square Enix and Disney.

Keen-eyed fans pointed out in the trailer something similar to the AT-ST walker, a well-known attribute of Scout transport from Star Wars: Episode VI – Return of the Jedi.

So, curiosity prevailed, and Kingdom Hearts fans compared these two images and, as they believe, found similar details.

Moreover, the forest location resembled the forest moon of Endor scenery from Star Wars.

It is worth mentioning that characters and settings from other Disney worlds appeared in the game. Not only Disney but also Marvel and Pixar crossovers were noticed: Aladdin, A Nightmare Before Christmas, The Lion King, Pirates Of The Caribbean, Big Hero 6, Monsters Inc, and many more. Moreover, Disney already planned to issue Star Wars content-based mobile games. So, everything is possible.

A new look of Sora and other characters in Kingdom Hearts 4 can be no more than just a desire of developers to step aside from the generally accepted animated appearance of heroes and make them more action-films-like. Sora's new look has nothing in common with the emergence of new characters or features in the game. The proof is the presence of other worlds characters in previous Kingdom Hearts seasons that didn't lead to Sora's look changes.

Let’s not get ahead of ourselves, as the game is only in the early stage of development. By the time of official release, everything can change, be cut, or developers can possibly add new issues.
