I think it might be the other way round. From the article: ‘This massive, evil-eye-popping miniature – if you can even call it a “miniature” – won’t be out for a while yet.’
Between that and the fact it didn’t show up in the CSM rumours that were spot on, I think it’s probably coming with the StD book in the winter and they just showed the CSM one now because the kit leaked anyway and people were asking about a CSM one.
