The images are starting to flow a little early for next week. The link are apparently from a forum in Poland, and were sent in to me here since I can't speak the language. This is the cover for issue 51!
You can get a great view of the new Stormfiends, and from my accounts, they look they have a 40k flair to them. I personally like them, and wish I had a skaven army. (my only fantasy army is Vampire Counts)
