Cyberpunk had several hours of 'raw' gameplay footage before release too. And of course, that really had nothing to do with how the final game played.

If they were trying to conceal how broken it is, they'd be releasing "doctored" footage that shows the game in as good a light as possible - again like Cyberpunk, for example.

BF3 didn't have MP gameplay before the beta at all either. BF4 did, and it didn't seem even remotely as buggy as the final game. BFVs pre-release gameplay and even beta was (arguably) better than the launch of the game too.

My point being; whether they do or don't show gameplay right now really isn't any indication in either direction at all. They could not show gameplay and the game is great, they could show gameplay and its a shitshow.
