Found the detailed financial report on Bolter and Chainsword, but it was also announced by GW.

"Games Workshop has entered an agreement with Amazon's Content Services subsidiary for the prospective development of its Warhammer 40,000 universe into films and television series, alongside the associated merchandising rights. The deal grants exclusive rights to Amazon for film and TV series set within the universe, as well as an option for exclusive rights in the Warhammer Fantasy universe down the line. "Games Workshop and Amazon will work together for a period of 12 months to agree creative guidelines for the films and television series to be developed by Amazon. The agreement will only proceed once the creative guidelines are mutually agreed between Games Workshop and Amazon," the UK company said. It added that it will make no change to its forecast for its financial year ending in June. Games Workshop had announce an agreement in principle with Amazon in December last year."

Bare in mind - Amazon did create The Boyz, which is a phenomenal show. And with henry Cavill at the helm - I have faith.

Wow Henri Cavill is going to be Executive producer?

That's very good. This guy is a fan from the various interviews where he mentionned warhammer (and total war warhammer as well) and I would say it's telling that he had to quit The Witcher series due to "creative differences" with the show producers who veered too far away from the source material to his taste.

To be clear, it has never been stated that way but that is what I read between the lines. For example, there is a comment that he had a lot of grunting to do but in the Witcher books, there is a lot of reflexion from Geralt that is never translated into the show.

As far as I'm concerned, Rings of Power is a crime against human cultural heritage. In general, one should never expect a faithful adaptation from Amazon, be it in word or in spirit of the work. That being said, they do occasionally produce decent and even good-ish tv shows. Unfortunately, even the best of them aren't free from consequences of the uncivilised policies Amazon put in place. But to be fair, in my opinion, GW too changed for the worse in the last decade.

I do not anticipate anything better from the small screen Warhammer. Mr. Cavill may have good intentions, but I think some things might be beyond his control.
