Yeah. Abared and Tyranno Ranger appear to warn King about the arrival of "Space War God Bordos", who aims to destroy them all. He uses the revengeful feelings of past Dinosaur Sentai villains to create "Neo Grifforzar"(Goldar) and "Neo Gailton"(Zeltrax)... and resurrects Enter and Escape! The Kyoryuger team up with the Go-Busters to face them! Also, there's a picture of a mecha battle, and it seems to be only with the robots of the dinosaur teams, with the Go-Busters standing in the Kyoryuger's cockpits (although without pods of their own, unlike Wizard in SHTZ).
"Let's resurrect the villains who are actually relevant to this movie and then this one guy because last years' team has to be in too". Really, it sounds like Enter here will be basically like Basco in Vs Go-Busters, just a grunt for fighting scenes. The entire plot seems entirely focused on the dinosaur teams. At least, going by the early summaries.
