So in the know he has to "think" what a mega corp may be "trying" and let us know of those thoughts (which are different to something he "heard").
But sure, it makes some sense the studio that made most of the games, even with some devs gone, is making the next one too, even after the Suicide Squad dud. Getting back to what worked etc...
Batman didn't work with a new studio either given Gotham Knights anyway.
People like making a big deal of devs leaving a studio but that happens constantly, it was also said when Retro Studios leads moved on to form Armature (which hasn't done any equally great original work yet, Recore being the closest they ever got) but Metroid Prime 3 still turned out ace even if it's not people's most favorite in the trilogy, as did the Prime Remaster and their Donkey Kong games too, so hopes are actually high for Metroid Prime 4 as well now that they're back to working on that instead of a different studio doing it. Maybe Rocksteady can bounce back too.
