Someone on r/primos said this in regards to Primos’s current status: “Disney wants to prioritize its three biggest series: Phineas And Ferb, Big City Greens and Kiff. P/F was recently revived”

I sometimes think the same thing as well, and I personally find the P&F revival impractical for a complex number of personal reasons.

And someone told them about rumors of Disney planning revivals of SVTFOE for various reasons.
