Playstation shipment history. Milestones incoming. PS4 required!

[ZaP~]

This year certainly will not be the lowest since there are still plenty of weeks to go for the ending of fiscal year 2012. but agree with the notion that if Sony doesn't release PS4, they are going to be on a tight spot.
Comparative (separate) graphs for Microsoft and Nintendo could be pretty interesting, i'm pretty certain this could be a trend for the three companies.
