Amid a 91 million euro marketing blitz, Nintendo's GameCube hit retail shelves in Europe at midnight last night. According to company representatives, initial sales figures look promising. Specifically, approximately 10,000 units were sold within the first two hours of availability in Britain. An estimated 50,000 preorders were also accepted for the console in the weeks leading up to launch. The GameCube is priced 100 euros less than Sony's PlayStation 2 and Microsoft's Xbox, both of which are already available on European shelves. Nintendo has already shipped 500,000 GameCube units to retailers across Europe, with another 500,000 expected to ship over the next eight weeks.
