Warhammer World is having their grand opening this weekend. If you're a Games Workshop fan and in the area, it might be worth your while to stop by. They've got some brand new products coming out that won't be available anywhere else. Special note should be made for any Ultramarines fans, as one of the minis is their chapter Primarch. There's also tanks a robots and all sorts of fun things.
Along with the Primarch, you'll also be able to get the Horus Heresy Book 5, the Mars Patterns Warlord Titan, two new Space Marine Command Tanks (a Rhino and a Land Raider tricked out with more satellite dishes than an NSA surveillance van), and the special Princeps Majoris mini, which is an event exclusive.
