it would be cool with power ups we like to see.

Wait. In the preview for the next episode, we see the Battle Caesar Robo is back AND ZenkaiOh JuraGaon wielding the Zenryoku Zenkai Cannon. And TwokaiOh is back as well. Both forms. Interesting next episode.

How did it take me this long to realize that Magine could pilot this formation?

Can Zenkaiser wield the Zenryoku Zenkai Cannon while in his Giant form?

Probably!

Aside from the upcoming episodes and Don Momotaro's cameo appearance, are there any other updates of Zenkaiger for 2022? What about Super Sentai Movies for this year? Aren't they gonna be released or announced by Toeijust yet?

A very bad news: Takuya Sato, Vroon's VA, has been tested positive for COVID-19 Coronavirus Omicron Variant. Currently, he's at the quarantine and we hoped and pray that he'll be better like Rio Komiya (Juuru Atsuta/KiramaiRed) did. Get well soon, Mr. Sato!

He'll be fine, no need to be a worry wart. The only thing we need to be concerned about is if he's going to be missing any episodes.

Aren't they almost finished anyways? I heard DonBrothers starts airing on March 6th.

There's still post production like voice overs which happens like a week to 2 week thing. It's why Gege had no voice around the same time his original actor left the role.
