I'm pretty sure the 360 dominates the PS3 in the UK as well. And if you've heard that is a pretty big market.
yup, UK is probably the second best market for 360 but, that's it, the rest of the world ain't at US or UK levels, maybe canada or australia. 360's awesome sales are too concentrated on certain territories, so i doubt they maintain their ratio there.
ANd yes, hw sales are usually tied to sw, but there are fluctuations, not everywhere games sell the same.
