I know it will have cross save from ps4 to ps5 and xb1 to xsx. But will Cyberpunk have cross save from PC to console and reverse?

Maybe. Chicken counting before hatching.

Not that I'm particularly in the mood to support the practices of CDPR at this time.

I get that they broke their promise and instead made the developers have to work on it just like every other title, which really does suck when they were trying to prove that they could do things better and differently. And voting with your wallet is one way of saying that it's wrong. But the reality is that the people who get punished by low sales aren't the people who broke their promise but the devs who had to work on it. The people who are in a position to screw other people over already have golden parachutes no matter their performance, the people making it have their bonuses tied up in how well their product does.
