Guys, would you please stop panicking about the movie before it's even finished?

The Go-Busters will for sure play a major role in this movie and not just have some lame cameo. Not only because they're part of the TITLE, but because they are not unpopular enough to reduce them to minor characters. If that was the case, they would have done so in Go-Busters vs. Gokaiger. Besides, the ratings are generally low these years- Kyoryuger may work a bit better with the fans, but it is far from the ratings Sentai used to have.
Also, there is a cast list that says Jin, Enter and Escape will return- if this IS true, we can be pretty sure the Go-Busters WILL be important enough to bring all of them back.
As for the other Sentai, I'm sure they won't make a dino-party out of this movie. The Zyuranger cast has mostly retired from showbusiness and Mochizuki Yuuta, for example, is in his late 40's (the Abaranger cast has also aged quite a bit)- they probably won't do a lot of action scenes out of suit anyway and I'm pretty sure they rather have a function as advisors anyway.

CALM DOWN. PLEASE.
