@Sean Reeve it’s the opposite, Dice have confirmed they won’t be adding Jango and Mace anytime soon while voice lines among other various things for Ahsoka and Ventress have been found in the game files, even Dice have strongly teased them coming to the game for awhile now. they will likely be added in the autumn or winter of 2020.
If they and Jango the time the darkside has two jet pack users and the light side have none so that will make the game unbalanced so Dice is not going my to add Jango but Windu would be nice
While I'd like Windu and Jango in the game, I'd much rather have Ahsoka and Ventress. The Clone Wars season may be over, but that won't mean that additional Clone Wars content won't be arriving in the future.
