At the final hour, the planned Injustice 2 PC beta has been pushed back. People were supposed to get an opportunity to sample the port through Steam beginning October 25, 2017. However, a post on the official Twitter account last night announced it would not be taking place as scheduled.
No details or explanation have been offered for the Injustice 2 PC beta delay yet. They will apparently be shared at a later date. There has also not been any information as to whether or not this delay will have an effect on the tentative Fall 2017 launch window.
Injustice 2 is available for the PlayStation 4 and Xbox One.
