Gokaiger-like sentai
 

It's possible we could have another sentai like gokaiger ?

You mean a big anniversary special? I doubt we will see another big one for a long time. I doubt we will see one for the 40th anniversary since Gokaiger is still recent and I doubt Toei wants to do another repeat of a similar season. I think another Legend War could happen for the 50th anniversary. I hope for the 40th anniversary, we could get a 2016 Sentai vs. Super Sentai movie or special. I won't mind having Naoya Makoto back as Akaranger.

Nope i don't think so. That feels like a one time thing.
Although i could be wrong and we get another one for the 45.

Not likely, at least not until the 50th anniversary or some other big number.

Really unlikely. I don't think they want to make the concept of the Sentai crisis crossover wear thin on the audience.

And I think the Gokai gimmick of changing into past rangers is going to be Gokaiger exclusive.

I think something big could happen for the 50th, but I still don't think it will be Gokaiger big. That was bigger than it was supposed to be due to all the former cast members wanting to raise the spirits of the people after the storm. Toei literally rewrote the story of the show to fit all the cameo requests they got.

So that season was that way by complete luck/misfortune (how ever you want to look at it). I think the next big season will have cameos, but not like we got with the 35th sentai. It would be cool for it to also be in the VS universe though.

If you mean an anniversary series that brings back lots of veteran Sentai actors? Probably not.

If you mean a Sentai series that's good? I certainly hope so, but the last three years haven't been promising.

We'll certainly see a season that pays homage to seasons past for an anniversary, but on the scale of Gokaiger? I doubt it.

We are gonna have to wait until about either the 50th or 55th anniversary
