Plus add the fact that they generally don't CARE if they sell on the Connect store right now. This may change rapidly though as more and more readers start to hit the mainstream and become an accepted distribution method. Between the branding of Sony with the Connect store (general awareness) and the online presence of Amazon (for online people) coming into play, publishers may be forced to take a more serious look at their final product presentation.

This would be even more rapid if they were to start utilizing on-site feedback per book. (Product feedback being something most publishers have none of.) They would notice a dissatisfied customer more if said customer could point out better products from competitors.
