From Toku Insider:
GET YOUR GRAIN OF SALT READY.
A new rumor has popped up that says the 2014 Sentai will be rescue themed (like GoGoV):
Title- Tokubou Sentai Kyuumeijya (Special Protection Taskforce Life Savers)
-Another Rescue Sentai, in the mode of GoGoV
-A further try at the "realistic look" attempted by Go-Busters, with show set up akin to RescuePolice
-The number of rangers in the show will be 9, using the pun "Kyuumei" (Life Saving) and "Kyu" (9)
-The 9 will be divided up into teams, like the Gouraiger and Go-OnWings
-There will be no main enemy, but a Rogues Gallery like Dekaranger
Along with news of a "Rescue Sentai", comes a rumor about the Zyuranger
actors guest starring during September episodes of Kyouryuger. Mei's
actor previously stated the cast would make an announcement.
