All I know is: Do we need it? No. Do we want it? Maybe. Will we watch it? Heck yes!
I'm curious if they're going to ask Nathan Lane and Ernie Sabella to reprise their roles. I feel like Sabella would, since he's still voicing Pumbaa on The Lion Guard. At the same time, another comedy duo who already get along well could also provide some fresh comic relief. (My mind immediately goes to the guys from Flight of the Conchords for comedy duos, but I have no idea if they'd be appropriate; or would even do it, other than Jemaine Clement having done some Disney voices.)
