Boston, MA: 24ms (Northeast US)
Miami, FL: 33ms (Southeast US)
Frankfurt, Germany: 109ms
Residential pings will be a bit higher obviously and may not have as good routes as these. Hopefully it's obvious that not only would a huge percentage of North Americans be getting stellar latency, but the impact on European players may have been reduced significantly enough to allow them to stay on their preferred server.
