There, I clarified:
Wii U sales "shipped to retailers, a lot of stock sitting on shelves":
1 month: December 31st, 2012: 3.06 million
4 months: March 31st, 2013: 3.45 million
7 months: June 30th, 2013: 3.61 million
10 months: September 30th, 2013: 3.91 million
13 months: December 30th, 2013: 5.86 million
PS4 sales "shipped to retailers, all of the stock sells through super-fast so it's essentially sell-through numbers":
1 day: November 16th, 2013: 1 million
2 weeks: December 1st, 2013: 2.1 million
1 month: December 28th, 2013: 4.2 million
3 months: February 8th, 2014: 5.3 million
The sales trajectory is ridiculous compared to Wii U.
