After some nice PM's regarding this thread (surprisingly enough), I decided to add some more stuff.
Okay, the polls. http://www.vgchartz.com/poll/results.php
If you only want the hard numbers, and the conclusion I write, skip over the next underlined area.
_______________________________________________________________________________
If the polls were correctly created, and there was no bias, they would peak at the middle options, and have lower on both sides.
This is almost the case with the Wii. It peaks at 40-41M, and is lower on both sides of that. On X360, it is far, far on the low side, and with Ps3 it is about even with everything.
Okay, now, I'm trying to do an analysis.
The total who vote for the lowest option are rabidly against the console.
The ones who vote for the highest are just as much pro the console.
The ones 2nd closest to the end is pro/against the console, but are probably realistic.
The ones in the middle are so unbiased we're going to have a problem determining.
Okay. Starting with the Wii.
16% voted for 36-37M. That's out of the question, and thus the people who voted for it are obviously trying to lower the average.
12.5% voted for 46-47M. That's slightly more likely than 36-37M, but far from likely.
This means that about 1/8 people on the site are unrealistically pro the Wii, and about 1/6 are equally silly against it.
That seems logical, considering the Wii is the most hated console ever (at least on the Internet overall).
The ones one inside that are relatively equal to the previous, and just build up under the same argument.
Over to the Ps3.
15% voted for 17 Million. That's equally unrealistic to the Wii's lowest option, and has the roughly same average.
17% voted for 22 Million. Not realistic, probably about as realistic as the Wii hitting 46M, but this is perhaps slightly more realistic.
The first number was higher than I would have expected. 1/6,5 are greatly against the Ps3. This is a surprise to me. I had figured it should be around 1/10, but the "hate" against Ps3 is on VGChartz almost as big as with Wii.
1/6 being too pro the Ps3 seems probable, considering my previous assumptions (in OP), have said that there are sligthly more Ps3 owners than Wii owners on the site.
Both the two above seem to have slightly high numbers, considering that the numbers are opposite for the other 2 (2nd furthest out ones). They're at 14% slightly against Ps3, and 13.5% slightly pro it. So realistically, they should both be a bit lower.
Almost finished. 360 now.
This one has a problem though. The options are a little high.
Still, I'll try to do it.
36% voted for the bottom opinion for X360.
36% aren't unrealistically against it, but still - it shows that there are more X360 "haters" than Ps3 and Wii "haters". Realistically, this should be ~ 1/4, or 25%.
Also, 5% being unrealistically pro the 360 is wrong, as the options are too high. We should rather add the top 2 options together, and subtract slightly from that. Some somewhere around 8%, or 1/12 are too pro the 360.
___________________________________________________________________________________________
So to sum up the numbers.
Wii: 14-18% are overly negative against it. 10-14% are overly pro it.
Ps3: 13-17% are overly against it. 15-19% are overly pro it.
X360: 22-28% are overly against it. 5-10% are overly pro it.
So if we take this, we can make an assumtion that:
1/4 of the site is Wii only owners.
1/3 of the site is Ps3 only owners.
1/13 on the site is X360 only owners.
Around 1/3 of the site own multiple consoles.
I also find this kind of comforting, as at least half the site is able to make founded predictions, which is far less than I have had a feeling it was lately.
The "who would win in a fight" also suggests that most of the numbers here shoudl be correct, although the poll suggests there are slightly less Ps3 owners than I suggest here.
