Even though I don't know anything else about the show, I reckon it has a decent chance of seeing the light of day in 2007. Why?
- Dayna was the lead animator for another flash animated series, "Pinky Dinky Doo," which preemed on Noggin on April 10, 2006. Plus, she worked on "Blue's Room" & "Blue's Clues." I doubt that Viacom would waste her talent.
- Dayna started working on "Pinky Dinky Doo" in January 2005, and one month later (February 9, 2005) Viacom filed its first app with the USPTO to protect "Pinky Dinky Doo."
- Dayna completed her work on the pilot for "Umizumiz" in March 2006 and one month later (April 20, 2006) Viacom filed for trademark protection.
Update (9 Mar 2007, 6:59AM PST): Thanks to a commenter's tip. Here's the link announcing that Nick has picked up "The Umizumiz." Congrats!
