ASDA is the UK name for Walmart. If Walmart hadn't bought ASDA and made it what it is today then they would've just bought another company for their UK venture and it would be in place of ASDA as being the UK's second largest supermarket. I don't see why people are arguing about this...
I'll reply to everything else later.

Wii U will sell under 7m in 2013 - I was right
