Blizzard's response to additional level 60 content for Classic WoW..
"Anything is on the table. This is a love letter to our fans. If the fans have a desire for something, it would absolutely be considered. We're certainly not planning to do that today, but if people want more, we can talk about that. We'll cross that bridge when we get there."
- Patrick Dawson, Production Director Classic WoW
