Kinda think we would have heard about that happening. But its not impossible...
I tend to agree. I think CDPR went through the normal certification process and it passed, and there's no indication 8 days after release that the certification was faulty and that the game is causing hardware problems regardless of whatever else may be on the table to debate.
And that's actually good news for both sides really. It would be a very bad look for CDPR to have their game damaging consoles. It would probably be even worse for Sony if they certified that the game wouldn't and it ended up doing so anyway.
Edit: Essentially, the certification process appears to be a non-issue in these discussions at the moment. it worked as intended for both sides.
