I don't think she is. Just started with covering Olden Era, as far as I can tell.

Official channel would be Unfrozen's channel (the dev):

The video I linked before sums up the 2 QA sessions from the official channel, which is over 2 hours in total. Feel free to watch them in full.

A pretty insane announcement about the music for the game:

Heroes of Might & Magic: Olden Era — Music Announce (Paul Romero, Cris Velasco & Heroes Orchestra)

There have been some rumblings that Romero was too busy for this project. Turns out those were not true and so the legacy of the music maestro in this franchise continues. Even better - Chris Velasco will also be participating on the project and they even announced a cooperation with the Heroes Orchestra.

Pretty much the best case scenario imaginable regarding the music for the game.

Here's the wishlist entry for the game:

EDIT:
Here is also a part of a livestream where there were short interviews with Romero and Velasco:

But I doubt that Ubisoft will bring the game here.

I'd be happy if the buzz around the new game resulted in them at least releasing VI and VII here.

nice!

We'll see. Early access on Steam is confirmed to not require Ubisoft Connect. If that lasts through to the full release, I don't see it as being impossible once the game leaves early access. Though that will probably be in like 2026 if I had to guess.

Doesn't have VII - and maybe even VI - a lot of online tie-ins that need UPlay to function and without them one has just a half of the game?

Hope dies last...

I honestly don't know. Since they weren't available DRM-free I didn't look into them much. I just assumed it's the more usual case of "needs uplay-or-whatever-it's-called but it could be removed". But you may be right, maybe it's worse than that.

Well, now they have officially included her on their channel :P
Devlog #1 | Templates in Heroes of Might & Magic: Olden Era

Not sure if she is hired per se, or just collabing with them on the videos.

Story trailer. Watch in 4K because due to the art style, the Youtube compression absolutely kills it on anything lower.

I noticed the compression too; YouTube really should offer one quality based on bitrate / compression and one on resolution so users can decide what works best for them. As for the trailer, I liked it overall, love the art design and style but at the edge of being generic fantasy in a way. Very excited for EA release!! Taking a break from gaming for personal reasons but if there's one game I have an exception for, it's this one.

Rumor is that EA is expected to last a year but after 1.0 release they will add Ubisoft requirement unfortunately, that means an unlikely release on GOG for a long time.
