The translation's a little rough:

The popular series Shinkenger will return through V-Cinema! This sentai has the first female red to show up, the first sentai 3-D movie shown, and the first meeting of 3 different sentai teams in Shinkenger VS Go-Onger. Thus, it has been recorded as a smash hit. To answer the fans, a special OVA will be released after the conclusion of the series. The cast of Shinkenger will face a Maximum Pinch in this original story which leaves them in period play costume...
