Forgworld released a news letter with a couple of teaser pictures of upcoming models. Take a look below as we can only guess at what these could be. In fact because of how 40k is we don't know if they are good or bad guys lol.
So while it appears to be power armor for sure we don't know too much more. Also it looks as if there is another vehicle coming down the pipe and Forgeworld does make some nice vehicle kits. Although a bit pricey.
