As we know, it's called Megaforce, and it's going to be out at around 2014. Now I haven't watched Power Rangers since Timeforce, but I caught a few glimpses, and it was meh.

Now I know it's not aimed at people at (presumably) our age, but what do you think? The idea of having historic rangers returning sounds awesome.Power Rangers Megaforce is the confirmed name for the next season of Power Rangers. The season will celebrate the 20th anniversary of Power Rangers. The Official Press Release has confirmed that Power Rangers Megaforce will be based on Goseiger.
Power Rangers Megaforce will be a completely new and original storyline based on 5 high school teenagers saving the world. The show will continue to use Sentai footage, but the story will be original. This will be the anniversary season. Power Rangers Megaforce will surprise fans. The 2014 season will also be "crazy". RoboKnight (also known as GoseiKnight from Goseiger) will make an early appearance in the show. An article in Kidscreen confirms that historic Rangers will make an appearance in Power Rangers Megaforce. Thanks goes to Tommy Lawson (RangerCrew) for finding the article.
The second season, also known as Power Rangers Super Megaforce, will feature Gokaiger content. There is no confirmation whether the Gokaiger suits and morphers will be used to morph into the past rangers. We may see Goseiger suits in both seasons. The Legend War will be shown in Megaforce. In the two marketing teasers that I saw, I noticed two easter eggs: Gokaioh and the Legend War.
Five high school students are called upon by the all-knowing Gosei to defeat a new evil determined to destroy planet Earth. They will become Power Rangers Megaforce. Using their cards, they will unlock all-new weapons, zords, and megazords. The battle has never been greater. The villains have never been more dangerous. And the Power Rangers have never been so strong.
Unlike Power Rangers Samurai, there will be last names and a city name in Power Rangers: Megaforce.
The mentor's name is Gosei, which was named based on the fact that the cards have the word "Gosei". We may be seeing the return of the Goseiger Cards. No confirmation on new cards, but we may be seeing them if Power Rangers Megaforce is a hybrid.
For centuries, groups of brave warriors known as Power Rangers have been called upon to protect our world from evil. Now, the future of humankind rests in the hands of a few ordinary teens with one extraordinary destiny. The 20th Season of Power Rangers will include flashbacks, weapons, and characters from previous seasons, and promises to be the most exciting season yet!
Power Rangers Megaforce premieres early 2013 with 22 episodes including holiday specials. The second season of Power Rangers: Megaforce will have the same number of episodes.
