According to a post by Ryoutarou of RangerBoard, we may be getting a Shinkenger Mini-Series in 2011...
So this is interesting, found it while making rounds on Japanese sites. The image itself isn't purported to be official, the information is.

Rough translation, courtesy of Dukemon:
My best at a translation right now:
Shinkenger Kokuki Senki (Country Record War Record):
13 episodes long
Recurring Cast:
Shiba Takeru/ShinkenRed played by Matsuzaka Tori
Ikenami Ryunosuke/ShinkenBlue played by Aiba Hiroki
Hanaori Kotoha/ShinkenYellow played by Morita Suzuka
Asou Makoto/ShinkenGreen played by Eiji Wentz
Satou ??/ShinkenGold played by ????
Kawakami Gensai/ShinkenJidai played by Yusuke Kirishima
I'll update this soon. I think it's exceedingly possible, given ShinkenJidai's character name, this may be set, somehow, in feudal times.
