I think its interesting to compare with last year sales for the same week
DS 110 328,379 (+83%) 14,381,637
WII 171,797 (+59%) 1,130,950
PSP 120,699 (+83%) 4,735,540
PS3 70,158 (-6%) 542,763
PS2 53,686 (+39%) 21,540,722
X360 19,993 (+10%) 305,307
GBA 5,845 (+48%) 16,649,843
278 1,258 (+49%) 4,014,908
Year to year we see the PS3 is selling about the same as last year ,the Wii has had some increment from 171K to 207K so some 36K units ,the PS2 as seen its numbers split in two in the final sign of decadence and the 360 doesnt manage even half the numbers of last year despite all the efforts of MS in that regards .The more interesting would be the portable system numbers ,while the PSP has managed nearly to double its sales the DS is selling considerably less that last year .So year to year we see improving the Wii and PSP specially the later ,a sensible decrease of the DS that remains the number one nonetheless ,the PS3 is about the same as last year ,and the PS2 and 360 are definitely on the way down .
