Maybe in a few years, Phineas and Ferb will be brought back for more episodes like what happened to Futurama. Even the lyrics of Time Spent Together give a hint:

Summer is done, and we've had out fun

but this isn't the end of our story

So for nostalgia's sake, let's just take a break

Sit back and take inventory

Dan and Swampy did say it's entirely possible the show could come back. And if it does they'll be willing to get back to it. But for now there's a sense "wait and see".
