Last summer I did an VGChartz 7th gen ratio poll, but I didn't get many votes. Maybe at the "start" of the gen things will be more active.
Keep it retail only, you can do your digital collection as a bonus. If you also bought digital retail titles you can add your equivalent downloadable retail games in your ratio. Note that first and third party are categorized by publisher, when in doubt check the worldwide publisher or who funded the game.
Here's an example of voting:
40% first party Nintendo - 4 Capcom - 2 Ubisoft - 2 Sega - 2 |
First state your percentage clearly so the post votes can be easily counted... and that's it really.
Happy voting!

RESULTS UPDATE (25/01/2015)
From the WiiU VGChartz sample more than 20% of those who voted in the poll also made a post vote (see a comparison chart below). The post votes are skewed towards 1st party titles, meanwhile the poll votes are bimodal (double-peaked) at both 40-60 and 80-100.
Be sure not to miss the other threads:

PS4

P.S. Just for reference, there was a WiiU thread done last summer: http://gamrconnect.vgchartz.com/thread.php?id=188993
