As of today Japan has a 1.54M lead over Wii, PS3 and 360 sales in the UK.
This year, Japan is 130k ahead.
The last 3 months of last year went like this
Wii:
Japan - 620k
UK - 655k
PS3:
Japan - 490k
UK - 475k
360:
Japan - 50k
UK - 775k
Total:
Japan - 1,160M
UK - 1,950M
So 790k in UK's favour. If we see a similar trend this holiday the gap will close by half.
