He can't help it, anyway.
They do have a second project, all we know about it is they're hiring members for it.. and they haven't got it signed yet. That leaves room for a FO3, but it also leaves room for just about any other RPG, really. I doubt it'd be another bioware hand-me-down...
of course, it's debatable whether this second team would have the input/participation of MCA, etc.
