Amazon U.S. April bestsellers and general Amazon-based discussion

[JRPGfan]

How long until they do a monthly update?
What are the chances of PS4 winning the NPD for april?

Current monthly for amazon shows the Switch at #8, and the PS4 at #11.
However the switch seems to be sold out and the PS4 is ahead in the hourlies.

Could the PS4 actually take April?
