So basically, it's done with 4x25GB layers.  It's still 25GB/layer, whereas this is an actual increase in the layer size, so potentially 4x33.4GB = 133.6GB quad layer BD.

Uncompressed video is gigantic, so no.  It will definitely be cheaper to manufacture, but the cost of discs to end users will most likely remain the same (pricing for movies etc were NEVER based on how much it cost to manufacture the actual product) - unless you're talking about piracy markets in various Asian countries.
BD-R(W) discs will get more storage for the cost, if they become popular.
