I'm hoping we'll see something entirely different for the next new Scrap Yard offering, especially as the DFLE and the S6 are likely to be released before that happens.
If Dan chooses from among his existing designs, my vote goes to the Scrapper 3 or the Scrapper Trail. Otherwise, I'd love to see him make an SR-77 version of the Tali-Whacker or a short-bladed EDC based on an Assault Shaker/Rat Shaker design.
A scrapper 3 would be nice. Then again so would a Scrapper 7.
