From
DakkaDakka's MongooseMatt, who has a good rep and talked with his rep (...

), has shared the contents of the new SC! bundles:
- Fyreslayers: Magmadroth, 10 Vulkite Berzerkers, Runesmiter (bit cheeky, as the latter comes from the Magmadroth kit).
- Beastclaw Raiders: Stonehorn, 4 Mournfangs.
- Slaanesh: Exalted Seeker Chariot, 10 Daemonettes, 5 Seekers.
Fyreslayers is going to be hell of a deal if that's true. 50% off, the highest savings since the Stormcast SC!, when they weren't reboxed. There will never be any other reason to pick a Magmadroth on its own; you might pick a Carnosaur because it costs the same as the SC!, but Magmadroths are more expensive. They could just stop making Magmadroths on their own at all.
And yeah, add that Runesmiter is quite cheeky, however if you mount him on a Magmadroth, you will have enough pieces to build a Runefather or son; however, if you mount one of them on the Magmadroth, you will have spare pieces to build the other one and the Runesmiters on foot, so you will be able to build up to 3 Fyreslayer heroes, which, now I'm thinking of, that might've the reason for why Magmadroth was that expensive to begin with.
I really want to grab some a Beastclaw SC! bundles. You'll never have to buy each of the two kits individually ever again (unless you want Mournfangs units at max size), and a lot of Beastclaw battalions need many Stonehorns or Thundertusks.
But it really bugs me because is just 2 kits. I love the kits but... is pretty much the same "problem" I have with the Eldar SC!; I like the contents of it, but I still feel like GW could've packed a Guardian squad too.
Still, it is a really good deal; just buy as many as you want or need to expand your army.
I suppose this also means that the Icewind Assault bundle will be replaced soon, which would be a shame. Unlike the previous bundles that had one or two finecast models, three fifths of the Beastclaw are finecast and are on the Icewind Assault bundle, and it has good savings (-$87 from $302/-£49.5 from £184.5) and obviously it feels like it has more variety when compared to the SC!
Now, I'm not complaining about the Slaaneshi Daemons one, but, "exalted" should mean something Imo. However, I have realized the Exalted Chariot is just a regular chariot and a Hellmower combined, so technically it has a duplicate kit on it but at the same time it gives you 3 options to build chariots. Definitively a good kit.
