Yes, a new set of Steampunk textures! Not only that, but sets 4, 5, and 6 (the new set) are now available as a combined Steampunk Textures Collection 2, for a discounted price of L$250.
A couple of samples pictures from the new set. There are actually four textures in each picture, but they fit together seamlessly, so it might not be immediately obvious!
You can get these in-world at the main store (see the SLURL link in the right-hand sidebar), or you can find them on the XStreetSL pages:
