You know - and keep in mind this is just wishful thinking - maybe they put the show on hold to work on the theatrical movie again. I mean, they said themselves that it was in a... development rut, but who knows how far production went on it before they had to stop; maybe they decided that they had already invested enough time, work and money into it to simply leave it unfinished. Or maybe the show could temporarily be on hold while they think about what they wanna do with the series now, I guess. Maybe Phineas and Ferb is just changing format.
