I think there is a bit of a misnomer that development only happens on one title at a time... Which simply isn't true.
A developer will have multiple projects in the pipeline.
For example... When Insomiac started developing Spider-Man, the writers would have already finished their work and would have been writing the stories for Ratchet and Clank... And then would have gone onto Spider-Man 2.
They wouldn't have waited around for development to finish on the first Spider-Man... That's just a waste of time and money.
Same goes for engine architects (Sound, Visual, Technical etc'), concept artists, director, lead designer, lead programmer, and lead artist and more... They won't stay on one project start to finish, they will start the ball rolling on the next project before the first one finishes.
