Series 1:
Fry
Bender
Zoidberg
Amy
Series 2:
Leela
Professor Farnsworth
Hermes
Calculon
Series 3:
Zapp
Kif
Flexo(or any other main character variant)
Morbo
And so on. I think after they run out of main characters, or maybe even before that, if they want the line to go on they'll want variants. And I can't imagine why they'd want the line to end before the new episodes start up, which is still pretty far off.
