Unfortunately, no. In fact, we don't really know anything about the new DLC in general! All we have so far is a high-resolution piece of artwork that From Software posted on Twitter and the title. As I discussed in my Miquella guide, the DLC is likely to focus on the demi-god Miquella, but beyond this, no one really knows. We don't actually know for sure that we'll be getting any new armor sets, but we can probably assume we will.
