I don't know if there will be any new info for you guys, but on SciFi Japan we've posted the high-res KAMEN RIDER X SUPER SENTAI X SPACE SHERIFF: SUPER HERO TAISEN Z photos and a translation of the press release Toei recently offered to press outlets…
The biggest problem is that these movies are easily dated. They focus mostly on the newest of the new Riders, and I'll never get over that. I'd kill to the film from the perspective of more classic Riders. God, imagine a story of this magnitude focusing on Black RX and the Dairangers.
