There’s still no word on exactly when the test servers for World of Warcraft: Legion will come back online following the winter break, but we can at least be certain that when they do come back it’ll be with bells on. A tweet from a Blizzard employee confirmed it yesterday:
No ETA yet for Legion Alpha realms returning.
Goal is to bring it up w/ new build, new content. Previous build we had out is now outdated.

What exactly the new content will entail is unclear, but there are lots of possibilities; the original test servers were capped at level 104, featured only one spec for the majority of classes, and didn’t feature Shaman at all. With no ETA, don’t bet on finding out this week; next week doesn’t seem tremendously likely either, but who can say?
