At peak we can get between 100,000 - 140,000 requests per second. The number provided by Diederik isn't very surprising.

If my math is right, that's 65M IPv6 requests a day out of ~8,000M, roughly 0.8%, which matches http://www.google.com/ipv6/statistics.html (though the latter claims to measure users, not requests). I imagine mobile users on IPv6 might be more aggressively cached by their providers, and they aren't requesting as many resources per page view, so Wikimedia's share of IPv6 users might be higher.
