More news about the GT5's sales on Finland. The game became Double Platinum (sold over 40k) after it first week.
To compare these numbers the World Of Warcraft: Cataclysm became Platinum after few days of sales and Halo: Reach is expected to reach 20k copies soon.
The user base estimate for Finland is about 200k... so the GT5 ratio is over 20%.
