I've counted polls and comments on July 30  to see who has the most. A weird turn was that Wii U dominated on both polls and comments. This shows that on this site at least... That most people have Wii U in their homes, PS4 has a slightly smaller number, and barley anyone has an XB1.

I have Wii U

I have a WiiU...

Getting a PS4 next month though

I have all three of them.
ps4, xbo, and wiiu.

I have a ps4, planning to get a wii u eventually

I only have a Wii U. I'd say it'd also be informative if you include additional options for people with Gaming PCs, but this is good enough for eighth gen console tracking :)

i have all 3

I have a WiiU so far and I'm hoping to get a Xbox One this holiday season!

I only have PS4, and will not buy any of the other two.

X1 in my house :). Might get a WiiU further down the road.

I have a PS4, leaving an open option for an Xbone somewhere at the end of the generation depending on exclusives (need to be better suited for me than the 360s library)
