PlayStation+Ninty+Xbox shipment history since 1995, UPDATED May 2015.

[eFKac]

This year will again be bad, there is really little to drive next gen adoption rate this year (MS and Sony should kiss Ubi for that Ass Creed) and Wii U is gonna Wii U I assume, handhelds are dropping like a rock, with Vita dead in the West.

2015 should see a good bump unless every delayed releases before April 2015, then FY 2014 might not be that horrible

Thanks for the data.
