This was leaked a month ago and their finished arc stood out in S7 as it wasn´t needed in the same way the Maul one was (turned into a comic years ago).
I know that the batch was supposed to show up one more time in the canned scripts so I hope that as much of those ideas as possible can make it into this show. Like the end of the Boba arc for example. That material can fit here. Also. The biggy:
A four-episode arc
[29] written by Matt Michnovetz
[30] with production codes 6.17
[31]–6.20
[32] starred
Yoda and the
Bad Batch on
Kashyyyk. At the "Untold Clone Wars" panel at Celebration Anaheim,
Dave Filoni talked about the plot of the arc. He revealed the characters would ride on giant ape lizards that were holy to the
Wookiees. In one scene,
Tarfful would ask the tree spirits for permission to go into battle against the enemy, which was a number of
Trandoshans[24]—including one named
Babwa Venomor[33]—and the
Separatist Alliance. To get the enemy out of some of their cities, they would have to burn some of the trees. The clones had no problem with it, but it was upsetting to the Wookiees. A part of the arc would be about the clones and the Wookiees finding a common ground to fight the Separatists. Some of Yoda's troopers would have his head silhouette on their helmets, and
Echo would now be part of the Bad Batch squad. A story-reel clip was shown at the panel, which showed the Bad Batch and other Wookiees battling a new beast that was based on
Kinraths from the
Star Wars: Knights of the Old Republic game.
[24] Only parts of the four episodes of the arc were made into animatics before the series' cancellation.
[34] Dave Filoni revealed at
Celebration Europe II that Yoda would be in the arc to give credit to the line "Good relations with the Wookiees I have" from
Revenge of the Sith.
[35] Matt Michnovetz revealed that
Chewbacca would have played a huge role,
[36] and that the arc would have contained some references to
The Star Wars Holiday Special.

Sounds hype to me. Rebels 2, I am waiting for you. You also sounded real.
