Mine also came today. I only poked through the first one so far but there's not anything surprising in the fluff bits. There are crusade roster cards for the units though which is nice, I guess. It occurred to me that it feels kind of questionable to have advertised all the freebies that it turns out we can't get because they've canceled it for a year.
It's not "cancelled for a year", they did a limited trial run with the intent to roll it out later if the trial was a success. This is how Imperium, Mortal Realms and Conquest have all run in the UK for the past three years.
Subscriber gifts come with your deliveries once the collection launches in full.
What they advertised when I signed up was not a trial run, it was a subscription. The first indication it was not an ongoing subscription was the email they sent recently. Nowhere did it say it was a trial run. I would not have bothered to sign up if they had.
Everyone signed up for a subscription, yes. Nowhere did they state when the subscription would start- the recent email saying that it would start (in the US) in early 2022 was the only time that Hachette actually gave a timeline. No one has not been charged (unless you managed to get in early and get the first two issues), so you are out of pocket no money. Everyone will get the subscriber gifts when the subscription starts.
The trial run was for the 4-issue run that was done in the UK, not anything to do with the US subscription- unfortunately it looks like Hachette didn't change their email explanation from what was sent to the UK trial-run recipients for the US subscribers, which is where some confusion may come from. It looks like anyone in the US who got in early enough to get the first two issues was sent the email that talked about the "limited regional run" being over that was similar to what UK trial run participants got after their 4 issue run- at the same time those that subscribed but didn't get in early enough also got an email that mentioned the limited being over without being charged. My thoughts would be that someone at Hachette just copy-pasted the earlier UK email and changed it to say USA. Nothing shady, just a company that is most likely having to re-evaluate the amount of interest they got (way more than they thought) and didn't send out the best email they could to inform potential subscribers.
