New week, updated charts. Now I'll wait for the japanese release to update these charts. They already show us the "slowdown" of each console. Wii U's is quite severe, whereas PS4 and Xone promise to keep an interesting (but not amazing) rate. PS4's supply issues seem to be gone. USA appears to keep the close battle between PS4 and Xone. The former has sold a little bit more in total even for the same number of weeks, but the latter is selling more in each of the last 3 weeks.
