En Masse Entertainment performed a huge information dump regarding the open beta weekend for PS4 and Xbox One version of TERA. There is a Console First Look page and video which provides an overview of console specific features and functionality.
There is also an information FAQ covering the specific details of the open beta test including client download size, date/time availability of the test servers, the type of content, available classes.
I haven’t powered on my PS4 for awhile now so I’ll probably give it a try.
