I found the link to these through the official Berserk page, www.younganimal.com/berserk . Shipments for these should begin in June-July, so they're pretty new, and likely still in stock for anyone interested in purchasing them.
I think these are pretty cool, but I'm still waiting for the ULTIMATE Berserk shirt before I put forward any money. The prices are exorbitant... This is the same company that made the Fantasia shirt as shown in this thread: http://www.skullknight.net/forum/index.php?topic=12292.0
