XBO in USA VS 3DS in Japan: who will sell more?

[Ryng]

I know that a home VS a portable isn't a good comparation, but i'm curios about you'r opinion!

For a comparation: both have sold 4.3 million first year.

Also, both console have a basis 30k-35k.

 

For me will be close, but i say 3DS

25,000,000 > 3DS JAP > XBO USA > 20,000,000
