I looked at the "both" and "neither" votes in previous polls, compared to this one, and I noticed two interesting things:
1. The percentage of people voting "Both" has decreased by over half. Back in March and April, 19% to 22% said they were planning to buy both. Now, after both companies have had their reveals, only 8.6% say they are getting both. The "both" votes have dropped by over half.
2. The "Neither" votes have doubled. Back in April, 8% said "neither;" in the current poll, 16.6% are saying "neither." I can see two possible explanations for that: 1) The reveals caused a lot of people to decide to hold off on buying either console for the first year or two; or 2) I added a qualifier to this poll option ("at least not for the first year or two"), which was not present in previous polls. That might have helped some people choose "neither" as an option, who felt a simple "neither" was too declarative or final.
TLDR: After the reveals, people voting "both" went down by half, and people voting "neither" doubled.
