To people who say that CDPR has LIED to them in order to sell them the game:
Your argument is self defeating for two reasons.
1. You have not purchased the game. There is no game at the moment, and there will be no game until May 19th. You have pre-ordered or in other words pre-purchased a game that is in development, and that means it can and it WILL change until the day that it is released. There is a reason it is called pre-order, and there is a reason you can cancel your pre-order.
2. You would not be here arguing that you were lied to and cheated If CDPR was in fact lying to you, because you would not have a clue that the game was "downgraded". Based on your own words, you can see from the new media that the game is "downgraded"! What this means is that CDPR is in fact showing you the real "downgraded" version of the game, and CDPR is encouraging you to cancel your pre-order if you do not like the new "downgraded" version of the game. If CDPR kept showing you media with the quality of the not "downgraded" version before release and released a downgraded game, then you could say that they lied to you and cheated you.
Conclusion:
1+2= cancel your pre-order and wait for the game to get released. At that point you can read reviews and watch walkthroughs before purchase, and CDPR cannot downgrade the game at that point (For an ungodly reason They may downgrade the game via patches, so to stay on the safe side do not download them!).
If you do not cancel your pre-order based on your own argument, then your logic has been "downgraded".
