Lying developers

[Copycon]

How much can a developer boast about "incredible in-game graphics", "radiant AI", "dynamic story lines" etc.  just to show the audience pre rendered movie clips, scripted sequences and still retain at least some credibility?

 Some games get hyped beyond comprehension and the developers are deliberately lying about the game's features. How far can they go and still "earn" your trust in future releases? How long/short is the memory of the consumers?
