There's a few references to older Bally/Williams games in Dialed In that I noticed. Here's a list I've observed.

Crazy Bob - Junkyard, Roadshow, Johnny Mnemonic, others?
Whirl Wind disaster mode - Whirlwind
Earth Shaker disaster mode - Earthshaker!
Sink Holes disaster mode - Roadshow, phone character is Ted
Voice for MANDI is same voice from Safecracker
Fester's chair (Addams Family) is shown in the theater during Drones multiball
Gumball machine (Twilight Zone) is shown in the theater during Drones Multiballs
Callout on making the first shot of Earth Shaker is MANDI saying "Oooo, bitchin'!"
Ball save "You can have it back"- Funhouse
"Hey, it's only pinball" - Funhouse
The laugh after the attacks on the flippers. This is like losing to the power in TZ.
After the Whirlwind disaster mode: "all clear, return to your home" Whirlwind
In Sinkholes: "You think it was gophers?"
In attract mode i heard (the same big voice as in whirlwind) : "feel the power"

There might be a couple more easter eggs in there. Any others that you've found?

EDIT: Updating the list.

Not sure if it's specific to White Water, but the music tempo and pace picks up as you run through disasters.... just like completing the rafts on White Water.
