Amazon US April monthly bestsellers and general Amazon based discussion

[Ryng]

Zelda was always on TOP 20 for all January-February, and for 2/3 March. (around 69 days)
First week: 350,000; NPD 515,000.

BloodBorne was on TOP 20 by starting of March, and for 1/3 of April. (around 36 days)

175,000 (half of Zelda sales) seem correct for me IMO.
