Rant drops a short to the point article of the confirmed changes we should expect with Phantom Liberty or/and patch 1.7, here is a snip;
Cyberpunk 2077 Phantom Liberty Revolutionizes the Game’s Cybernetics
The new expansion overhauls Cyberpunk 2077’s cybernetics, making armor dependent on the character’s cyberware. It used to be tied to the character’s clothing, so players had to sacrifice looks for defensive stats. Now, they can wear whatever they want without having to worry about making their character more vulnerable.
Cyberpunk 2077 Phantom Liberty will make cyberware riskier, too. V will have a limit on how much cyberware they can add before they get health penalties and other debuffs. This may also be patched into the main game. Some may see this as a limiting way to play the game, but it may also push players to be more deliberate when it comes to augmenting their characters.
