From their announcement:
Here it comes people…BLITZ! We release in mid-may 2011 for North and South America and Australia, and early to mid June for Europe. Situation Normal, All F&%#ed Up. Distributors and retailers in the Americas/Australia have been sent new product listings for retailer pre-order. European stockists will receive an email from West Wind shortly. Retail price of one of each of the new yummy stuff is about 138 bucks US. We’ll start a 20% off pre-order package deal on the Grindhouse website tomorrow for the Americas. Maybe some other goodies too.
