Yes, still available: https://us-store.wacom.com/Catalog/Acce ... undefined2
You have to dig through the store a little bit to find it. It is also available on Amazon, vistek.ca, bhphotovideo.com, adorama.com... I'm sure there are others.
Also, pen rotation still works in Photoshop and Corel Painter in Sierra.
Hope there turns out to be a simple solution to this.
