Path of Exile's expansion The Awakening goes into closed beta this month
Closed beta testing for the next expansion to Path of Exile is expected to launch within the next nine days.
This is according to a countdown clock on the official website, where you can also sign up for testing.
Gamepedia has plenty of information available on the add-on, such as the number of new skills, boss fights, and unique items which number around 90.

Thanks, Blue.
