I guess one country, even as big as UK is for Europe, is not a good indicator. But 3DS will have a massive launch, and what is more important, is that with many releases every month, it'll continue selling well for the whole year. Sure, in Dicember it could loose to Sony, but with its line up it'll be difficult to loose much.
I would like to know the numbers Nintendo estimates for FY 2011, 20 m doesn't seem too much to me.
