According to Deadline, the new Scooby-Doo series has officially set for release in 2019. The series will once again premiere on the Boomerang streaming service, though it may air on television at some point. There has been a slight title change, however. The series is now called "Scooby-Doo and Guess Who?" rather than "Guess Who, Scooby-Doo?" as previously announced by Grey Griffin, the voice actress for Daphne.
In the same vein as the New Scooby-Doo Movies, the new show will feature currently-famous guest stars from pop culture, both real-life and animated. Guest stars currently slated to appear in the show include Halsey, Sia, Mark Hamill, Chris Paul, Neil deGrasse Tyson, Ricky Gervais, Kenan Thompson, and Bill Nye, The Science Guy. Fictional guest stars include Batman (voiced by Kevin Conroy), Steve Urkel (voiced by Jaleel White), Wonder Woman, The Flash and Sherlock Holmes.
You may also notice that the series title card was designed based off of the original series' title card (Scooby-Doo, Where Are You?)
Sam Register serves as the series producer, along with Chris Bailey, who is perhaps most famous for his work on Kim Possible.
In addition to the Boomerang announcement of the series, Halsey discussed her upcoming voice acting role in the series during a recent interview with Billboard.
“I do it kind of on the low, I don’t put it under my own name,” she says. “So I do like Scooby-Doo and American Dad. I have like a weird voice, so I embrace it. So I’d probably love to get into something where I could be really animated, cause I’m pretty animated.”
In addition to the new series, Boomerang also announced that the remaining 11 episodes of Be Cool, Scooby-Doo! would be added to the streaming service sometime this year. The series has already finished airing in nearly every other country and the episodes have previously aired in a late-night death slot on Boomerang in the US.
A new Flintstones series, entitled "Yabba Dabba Dinosaurs" was also announced for release on the streaming service, and is also set for a 2019.
