Under James Gunn's vision for the DC Universe (DCU), the Super-Family is set to play a significant role following the success of his film Superman, which introduced David Corenswet as the titular hero.

James Gunn will write and direct the "next movie in the Super-Family" after the success of "Superman" this summer.

While, sure, Robin could still technically pop up in the next Batman installment, it's absolutely not confirmed. The only things we know about the next Batman film is that Robert Pattinson should return as the Caped Crusader and that the film will preparing to start production next spring.
