I think we’re approaching a point where games are going to be made like movies.

Teams assembled for one project, everyone does their bit, and are then discarded when they’re no longer needed.

Big publishers will probably have a pool of people they can push between projects depending on what’s needed. Ubisoft appear to do that, when you look at the credits in their games, there’s like 10 subsidiary studios involved. For smaller studios, you’ll probably be let go between games until you’re needed again. Maybe they’ll keep your information and rehire you because you did a good job of hard surface rigging or whatever last time. Maybe they hire an excited school-leaver to sloperate a clanker. Who knows.
