Well, interesting poll results so far. Counting a "both" response as a vote for each, so far it's looking like the regional vote split is:
Americas: 30 votes for PS5, 23 votes for XSX/S
Europe: 24 votes for PS5, 13 votes for XSX/S
Asia & Others: 7 votes for PS5, 4 votes for XSX/S
Xbox was initially competitive in every region, but it looks like the PS5 pulled ahead after the first day or so, even in the Americas. But as expected, the gap is a lot closer in the Americas than elsewhere, with 56% of respondents in the region intending on getting a next-gen system are planning on getting an XSX/S, as opposed to only 39.4% in Europe (for both regions, a bit over 70% of respondents who didn't pick "Neither" were planning on getting a PS5).
Another interesting result is that it appears that respondents from the Americas are more likely to go multiplatform. Over 50% of respondents from the Americas that are planning on getting a Series X/S are also planning on getting a PS5 (to flip that around, 40% of those planning on getting a PS5 are also planning on getting an XSX/S). For European respondents, only 30% of those that are planning on getting an XSX/S are also planning on getting a PS5 (or conversely, only 16.7% of those planning on getting a PS5 are also planning on getting an XSX/S). I wonder how much of that is due to the general disparity in buying habits between North America and Europe and how much is due to an actual increased likelihood of people living in the Americas to go multiplatform.
Of course, all of this comes with the caveat that we are dealing with a small sample size of 119 respondents on a gaming-focused forum, and in any given forum the relative popularity of a given platform within its population is unlikely to be reflective of its relative popularity among the broader population. Aside from the clear regional imbalances in platform popularity, these results are unlikely to be indicative of the actual results of sales we see early on.
