I do think this tweet is referencing KP4. PRISM was all about 'letting the light in', and this tweet is like a departure from PRISM (others siphoning the light she let in) and so now she's going electric.
She also tweeted the lightning bolt emoji when someone praised Rise's iTunes banners aesthetics on Rise release day.
The "S" in the Rise logo (both versions) looks like a lightning bolt, and the "R" looks like a reverse lightning bolt.
She made that comment about being 'electrified' by the Pulse survivor.
In a recent tweet Covergirl called her Blue Katy Kat Eye "Electric Blue" instead of "Perry Blue".
The new shoe line K•P logo looks like it's glowing/electric and the P kinda looks like a lightning bolt (bit of a reach).
There are too many signs now tho. Electric is coming.
