Dark Souls 3

FromSoftware has declared that Dark Souls 3 will out in April next year in Europe and North America.

A 'Network Stress Test' will take place on October 16th, 17th and 18th to play the game 'for various tech verifications'. This will only be accessible on PS4. 

You can register for the non-beta on the Dark Souls 3 official site from September 18th until October 4th. You can test it for stress and it can do the same for you.
