I think Indiana Jones is more early in development than everyone thinks. I also think Wolfenstein 3 must have been rebooted mid-development or put on hold in favour of Indiana Jones, at this stage, I'm tired of predicting it will show at every showcase for the past 3 years and it never does, Lol. MachineGames honestly isn't a very big studio either.
ID Software could take longer to reveal something if their next project is a Quake reboot. Roundhouse Studios is tiny and we know they're assisting on Redfall, they don't even have a website or any open job positions, I think there's a strong chance that they may simply be only a support studio for now. Zenimax is a 50/50, Imo.
Lots of Bethesda stuff released recently across most of their studios and they don't have many, and Bethesda has more than a few times had E3's which were low in quantity, I think there's a strong chance they take a little bit of a backseat and their time on some projects after Starfield. Especially because XGS should start becoming in a better position.
