1. Splatterhouse is expected to be released in Q3 2010, you can't expect to see none-approved videos that far ahead - and frankly why do you need to if it's that far away?
2. I watched 30+ gameplay videos from the beta of BFBC2 before I made up my mind pre-release. I didn't even glance at the official videos.
If a game is bad, there aren't boring bits they aren't showing you, you'll be able to see from the videos that the gameplay in general is bad. If all you watched were marketing videos of C&C4, then shame on you because I watched a ton of unofficial gameplay videos of the game before it was released, even though it's quite clear from the approved gameplay videos that it's a terrible game.
