Vista will only send two requests when it contacts a specific server for the first time. After that it knows which protocols it does and does not support, and will use only those. And if the end user system is only connected via IPv4, then it will not do IPv6 requrest at all (why should it?) and vice versa. In other words, the increase in traffic will be marginal, if even noticeable. There will also be no immediate spike, because people will be slow at actually installing the new system.
