Just to be clear: TBC servers or getting changes doesn't mean no "Museum" servers

Nope. People actually asked the devs if they’d be open to adding new content for Classic such as newer gear/raids/storyline etc. and their answer was a possible Classic TBC release. Hence our discussion in the other thread here:

TBC is on the table!

per the reddit AMA: “We’ve done most of the hard work by bringing back 1.12 so progressing to Burning Crusade would be a lot easier for us. Our plan is to identify everything we need to do should we ever decide to go this route. We want to be sensitive to the desires of our players. Some may want BC and some may not. We’ll be following the Classic community closely to help determine what our next steps should be.”
