Already updated the first post, and made the console comparison thread.
But I have more VGChartz data for Nintendo's home console from previous poll votes of the Wii era:
Wii 2010 to 2013 already saw a slight shift towards first party, nevertheless the VGChartz collection was still mainly 50-50. In 2014 WiiU's result had its maximum ratio in the 60-80 range; one year later (and with less third party releases) it's become a bimodal distribution between the 50-50 and the 1st party camps.
It will be interesting to see the further shift towards 1st party in next years poll
