Read all 24 pages, and i'm totally sure there's a lot of US/EU N3DS ready to be sold in their countries, and that means there's a lot of 9.x of them, so i'm not gonna rush buying one now.
Anyway, the only 2 games that are confirmed to have exclusives features for N3DS are Xenoblade Chronicles (which i have finished) and Majora's Mask, which stll we don't know exactly the new features it has. Also Smash Bros with better loading times and better FPS, not?
With my 9.2.0 and a Gateway i'm pretty good now ^.^
