Well obvious the bottom line for the current companies is they don't see value in it.
From the videos they provided, the production aspects of their promotional material is pretty limited. But since they already shoot some video, like features in pro or LE, you don't think it would be too hard to through on some gfx and make a little longer video.
In reality I feel someone like Stern enjoys the way they do it now, having deadflip launch videos, which I can understand not everyone is into.
Spooky has their features video...is this what you mean or more stylized, produced etc ?
