It will be updated regularly as more PS4 secrets are uncovered in the public, so visit often for the latest scoop. Please link to this webpage, rather than copy the contents.

The chart is semi-ranked from most important to least important feature, taking into consideration possibility of adding back a missing feature. Pink entries indicate not officially released.
