This year came Zyuohger, which was considered a return to form season from Super Sentai after the previous four seasons (Go-Busters, Kyoryuger, ToQger and Ninninger) were met with a divisive response from fans, especially coming after Gokaiger, which was an affectionate nod to the show's 35-season history.
Then next year comes Kyuranger, which is the first ever Sentai season to have nine members at the start. Not three, not four, not five, not even six, but NINE! It's also the first team to have a full-time female Green Ranger after a Extra Heroine (though starting out as a villainess) in Gekiranger and a movie-exclusive one in Ninninger, so Black is now the only Ranger colour to have no female Rangers (Gokai Changes and the sole female of the Neo-Jetman team do not count), which is the same for Pink being the only Ranger colour to have no male Rangers (Gokai Changes and Hououranger of the original Dairanger team do not count). And yes, it's the third consecutive season to have a male Yellow Ranger. Some people think the recent male Yellow Rangers are a response to Takahiro Omori's statements about the lack of Kyoryu Yellow in Kyoryuger and other don't think so.
Also, there will be 42 collectible Kyu Tama. 42 is in fact a reference to the answer to the Ultimate Question of Life, the Universe, and Everything from The Hitchhiker's Guide to the Galaxy. It is also the fourth (fifth if you count Deka Swan as such) Sentai season to have an Orange Ranger and first to have the Orange Ranger in the main team since Battle Fever J. The tradition of post-anniversary teams that start with three members since Hurricaneger is now officially broken.
Pretty much almost all (not counting variations such as Cyan, Navy, Crimson or Gray) colours are representing the Kyurangers except White and Purple plus the suits are in fact a nod to the Chinese tokusatsu series Battle Strike Team, mainly Giant Saver and Space Deleter. I commend Toei for revealing the suits and mecha.
