I really wanna know what the Wii would've sold if they had the stock available to meet demand at launch day in the UK. The PS3 had a successful launch, but it's not by any means phenominal. UK is Sonyland, so it was to be expected.
This could die off soon.
I don't think the Wii has been reliant upon the hardcore gamer type to drive sales. These casual users would never buy into the launch hysteria. These users will typically only purchase after playing with their friends. The Wii can penetrate into a largely untapped demographic instead of fighting over the same user base.
