While a few things are starting to get back to a bit of normal, we're definitely not there yet. As such, release schedules are still in a bit of flux. Games Workshop is having to move around their releases a bit, pushing them back.
From the article:
It’s still a pretty weird time for anyone making physical products and shipping them around the globe. There are loads of fantastic things on the way over the next few months, but we have to make some changes to when the next batch of incredible Warhammer releases come out, and we wanted to keep you up to date with everything that’s going on.
Everyone at Games Workshop is working really hard to get all of your orders to you in good time so you can continue to enjoy your Warhammer hobby, whether that’s via games-workshop.com or forgeworld.co.uk, your Warhammer store, or a friendly local gaming centre. With this in mind, over the next couple of weeks, there will be a short pause where we’ll have no new pre-orders. Have no fear, though – new releases will be coming your way before you know it.
