They didn't "lie" to us. Showing examples of how they want/expect the game to look and then having to pull back from that target during development is a reality of game dev, not an intentional misrepresentation of the game. If they're trying to sell a lie, why show the "downgraded" game more than a year out from release? Demos and previews are intended to give you a glimpse of the game in its current state, and we don't know what happens behind the scenes much of the time in between those states. It's not CDPR's fault that people cling to footage from two years ago as though it were some kind of soulbinding promise of visual fidelity.
Christ, do people even know what "lying" means anymore? These threads make it painfully, embarrassingly obvious how little most gamers know about the development process.
