GW just sent out an email reporting that something special for Orks and Goblins will be arriving in May.
To quote the posting:
Orcs & Goblins are one of the most popular Warhammer armies and it's not difficult to see why: they can field warriors of all shapes and sizes from tiny Snotlings to Giants, and every shape of Orc and Squig in-between. They have access to a bizarre array of war machines and mounts, and some of the most entertaining special rules of any Warhammer army. And thanks to their inclusion in the great-value Battle for Skull Pass set, are often the first army a hobbyist collects.
So this May we're celebrating the Orcs & Goblins in all their choppa-wielding glory. We're under orders from the Big Boss to keep quiet about exactly what's going on so be sure to check out games-workshop.com in April when all will be revealed and pick up May's issue of White Dwarf for an in-depth look at all things green.
