Amazon US April monthly bestsellers and general Amazon based discussion

[Ryng]

My March NPD prediction as for now:
PS4: 390,000
XBO: 240,000
WiiU: 100,000
...
I expect a -50% dropped for PS4, the same for XBO, and -40% for Wii U, so...
If my prediction are right, let's predict for April NPD:
PS4: 195,000
XBO: 120,000
WiiU: 60,000

I will probabily change this prediction...
