Are there any plans for Atomic Cartoons to work on a revival of Atomic Betty?

Yes! An upcoming revival of Atomic Betty will be in its pre-teen format because an additional 4 seasons with 192 quarter-hour episodes in 96 half-hour shows, plus another full-hour Christmas special, 2 "Atomic Betty Classics" specials that are parodies of fairytales with princesses, and the "Grand Finale Spectacular", are all being produced between 2015 and 2019, but takes approx. 2 years each to complete before being aired on Canada's Teletoon channel, Discovery Kids & Family in the United States, CITV in the United Kingdom, and Time Warner's Cartoon Network in a couple parts of the world, among other TV channels worldwide, and the following changes are being given:

New characters include Betty's mean babysitter Amy, Dr. Todd Phillips (and his son Art Phillips), Betty's other mean babysitter Max, Amy's little sister Cassie, Little Power Aliens A, B, C, D, E and F (and their father The Big Power Alien), the Giant Cadet Robot, Mr. Parker's wife and Noah's mother Mrs. Parker, the Parker family dog Baxter, Penelope Lang's mother Mrs. Lang, Amy's spoiled pet dog Palette, Amy & Cassie's parents, Max's sister and Amy's friend Fat Mae, Sparky's father Sparky Sr., Charles "Chaz" Lang and his best female friend Sam (both of whom have appeared in Atomic Betty: "Mission: Earth" a.k.a. Season 3 of the show) and several other characters.
Betty is appearing in her more-tomboyish normal look, wearing the following clothes on her body as her new usual outfit (On the Top of Body: Her yellow short-sleeve tee shirt with green highlights and a big green nuclear symbol on the center; On the Bottom of Body: Bright blue long-leg full-length "pants"/"slacks" with light blue cuffs on bottom; and the rest of her original usual outfit can still be worn on her body). She is no longer seen wearing her yellow sweater with a white shirt or her green knee-length skirt, so her more-tomboyish normal look will remain the same after the show's newly-upcoming revival. However, whenever Betty appears on mission as her Galactic Guardian alter-ego "Atomic Betty", she is still seen wearing her standard Galactic Guardian uniform.
Ashleigh Ball gets to provide the voice of Penelope Lang for the first time, impersonating Catherine Disher's role.
Megan and Sarah's voices are respectively much deeper and higher than their appearances in Seasons 1 & 2; therefore, their voices are being provided by Julie Lemieux and Tajja Isen respectively.
Noah Parker's standard Galactic Guardian alter-ego will be called "Atomic Noah", and the result is that he will replace Cadet Noah as his own alter-ego from the show's newly-upcoming revival onward.
The show's theme music from Seasons 1 & 2 will be remixed and rearranged, this time being performed by the Tajja Isen Band, which is being formed in 2015.
Betty's Mother herself still wears all of her usual outfit on her body, but her white tacky animal-printed sleeveless top is being replaced with her light blue short-sleeve tee shirt with white highlights and a big white collar, which can be tucked into the same pink pants she wears (except that a ring-shape belt buckle can be worn, and is exactly the same color as her bracelet, necklace, and earrings).
Noah Parker himself is never seen without wearing his bracelet, the same reason as for either Betty or her mean babysitters Amy and Max.

The show's creators will be interested in making its own revival, and so it will be produced by Atomic Cartoons, Breakthrough Films & Television, and TeleImages Kids. At the end of 2014 (and beginning of 2015), an additional 4 seasons of "Atomic Betty" and another 5 shows that are in the works by Atomic Cartoons are all in development, but can take 2 years each to complete. Other than Atomic Betty, shows being produced by Atomic Cartoons include a TV series adaptation of "Twinkle Toes & Friends" (which is being based on characters created by John Masse for Skechers footwear), and another 4 shows using Adobe Flash animation. These 6 shows are being planned to air on selected television channels worldwide, with the most typical example being a revival of the pre-teen format Atomic Betty TV show airing on Canada's Teletoon channel, Discovery Kids & Family in the United States, CITV in the United Kingdom, and Time Warner's "Cartoon Network" in a couple parts of the world, among other TV channels worldwide. "Cartoon Network" (and its corporate parent Time Warner) still owns the rights for Atomic Betty in some parts of the world, but not in most countries like those of the United States, United Kingdom or Australia, because the rights and ownership of the show have been sold to Sony Pictures; therefore The Media Club (which is being established in January 1, 2016, as a joint-venture of The Walt Disney Company, Hallmark Cards, and Sony Pictures Entertainment) is owning the rights to the franchise of Atomic Cartoons & Teletoon Canada's "Atomic Betty", and the first three seasons (78 half-hour or 156 quarter-hour episodes) of Atomic Betty are being planned for release on DVD by Shout! Factory in 2017.
