Best place in London to buy a Wii on launch day?

[muddy]

So I'll be in London on launch day (waking up in a hotel with a storming hang over if all goes to plan!)

Where's the best place to try my hand at getting a Wii on launch day in Londinium?

[dudesweet]

Im hoping Game on Oxford Street - as thats where me and my mate will be

Otherwise couple of big HMVs on Oxford Street also
