THR reports that, according to Disney reps, yes, it should be expected that Mena Massoud, Naomi Scott, and even Will Smith will return, but, with the script still in its early stages, no offers have been made to the actors at this time. One actor from the cast of the 2019 Aladdin remake whom I would especially keep an eye out for is Marwan Kenzari, who played power-hungry tyrant Jafar, because if he returns, that might be a hint as to what the sequel will be about.
