For now we only have a single image to base this assumption on, but it looks like the Super Hero Taisen GP film may be the second such film primarily about Kamen Riders, to feature Super Sentai!
A new magazine scan for the movie has surfaced showing what appears to be a Kamen Rider Drive Nin Shuriken! Thus implying that Shuriken Sentai Ninninger will indeed appear. On top of this is a silhouetted image of what looks like a new Shinobimaru style robo. One that could very well be the Tridoron given humanoid form!
Time will tell if this pans out but it looks like for now that we may have another special movie combo following in the footsteps of last years ToQ Oh Kyoryuzin featuring Den-Liner!
