With the success of the show, I sincerely doubt that Disney is just going to cancel Phineas & Ferb now when it's in its prime. Besides, Dan & Swampy are still so passionate about it. I think Phineas & Ferb could be the first Disney show to break that 4 season rule.

Hey, Disney had a 65 episode rule and that was broken. Who says the 4 season rule can't also be broken?
