Initially scheduled for September, Shadowlands was postponed to November 23, which as you may know is today! Well, while the expansion is indeed coming today in some countries, in others, it's actually tomorrow, as you can see in the official release times below:
In any case, Shadowlands will allow players to evolve from 50 to 60, through a new area that serves as Azeroth's afterlife.

We will be sharing our first impressions before the end of the week.
