According to Blizzards post Karazhan Gruul and Magtheridon from james's blog

According to Blizzard’s post, Karazhan, Gruul, and Magtheridon are the raids to be tested from these days until Friday. On pinnacle of the contemporary itemization choices, players will be allowed to Buy WOW Classic Gold  choose up consumables and whatever professions they want on the providers in Shattrath.

While the world is presently offline, it will maximum probable go browsing later these days once the raid trying out window opens for Karazhan. If those raid checks are a hit, Blizzard may look in the direction of Sunwell, Tempest Keep, and Black Temple for the future.

If all of the raid tests show a hit, we might get to mmobc.com  see an early Q3 release of the WoW Classic Burning Crusade servers. This is all hypothesis for now, however, thinking about that Blizzard themselves didn’t provide out a launch date for now.
