Any guesses as to when TBC Classic is released?
My guess is 2 to 3 months after Shadowlands releases for 1 simple reason: SL is likely to be a gigantic flop, so Blizzard will release TBC Classic to maintain a boosted subscriber number to givr shareholders the appearance of success of SL expansion.
Remember that when Classic released, WoW subscriptions world-wide quadrupled, making Classic much more popular than retail. Blizzard tried to hush this fact by disabling the API that census addons used, but the data was already out there.
Blizzard is trying to leverage Classic to get people to buy the garbage Shadowlands when all we want is a functional and supported Classic (eg, fix teleport hacks, start communicating with customers, etc).
