People misinterpret the "2 movies and 2 shows" thing.
io9 was among a group of journalists who spoke with Gunn and Safran about their new DC Universe and here’s what they had to say about, well, everything: new movies, old movies, new actors, old actors, continuity, you name it.

So how many releases are you looking at per year?
Safran: Probably two movies and probably two HBO Max series.
It's not a set in stone rule. There are probably years where there'll be more, years where there'll be less.
Even then though, The Batman Part ll IS a DC Studios production, so it does count. That'd be their second movie that year. 2025 forget it, there's nothing else to release except Superman and Peacemaker. I guess you can't fully rule out the possibility of another show getting released but they'd have to start on it right away and there's no sign filming will begin that soon for any other show.
