The five of Gokaiger briefly become Red Rangers in Goseiger vs. Shinkenger. Yellow became GekiRed, Blue became Bouken Red, GoukaiRed became Go-On Red,Goukai Green became Deka Red and Pink became Magi Red.
Shinken Blue, it is because they will be releasing the other color Ranger Keys in March.
It looks like the first episode will show a horde of Sentai fighting. 1/28/11 10:44 PM EST I sooo want this poster above.
