Week 7!
DS 06 -- 51,512
3DS 13 -- 99,806
DS hardware bounces back from its 2006 low, while 3DS hardware drops a bit more sharply than I anticipated. Neither console had any major new releases in these respective weeks.
Week 8 preview: DS sales drop slightly down to 43,765. This is the final week before the DS Lite launch. I don't believe any major 3DS titles were released the week ending February 24, so I expect 3DS sales to drop further. Thankfully, the following week is somewhat stacked with three major titles releasing, so that'll be a fun one to watch.
The tally thus far:
DS 06 -- 408,155
3DS 13 -- 875,683
Adv 3DS +467,528
