The timing of this news is unusual as Power Rangers Super Megaforce has not even premiered yet. In the past, new seasons of Power Rangers would be announced after or near the end of the current season. Whether or not the early news is a good idea, it's a risk that Saban Brands is taking as part of its marketing strategy. A lot of children are likely to be excited about a dinosaur-themed season. After all, dinosaurs are one of the most interesting creatures that kids think are cool and they love to play with dinosaur toys.
Now that I think about it, this could probably work. By getting people hyped up about Dino Charge, fans will crave it impatiently and then satisfy their urge by watching Super Megaforce in the meantime as they wait for 2015. Not to mention, stores could be stocking their shelves with Dino Charge toys in the Winter as they usually do with new Power Rangers toys. By then, kids will be going crazy for new ranger toys and parents will know what to buy for Christmas, especially when they are informed ahead of time about Dino Charge news.
The first season, Mighty Morphin Power Rangers, used the dinosaur theme which could very well be one of the most significant factors that catapulted the franchise to popularity as one of the biggest hit children's TV shows of all time. The most recent use of dinosaurs was in Disney's Power Rangers Dino Thunder in 2004 which delved into the theme much more with the rangers finding dino eggs, using dino gems as a source of power, riding on dinos during combat, and even going on field trips to learn about dinosaurs. Jason David Frank (who played Tommy Oliver from Mighty Morphin, Zeo, and Turbo) also returned as the rangers' mentor and high school science teacher for the season.
