I'm sure those developing these vendor page ideas really thought that this was going to improve how pages were going to display and allow potential buyers to get to the meat of what they want to know more quickly than before. In practice, this simply isn't happening.

I would have suggested - like when google came out with their new gmail thingie and Live, same thing - that a select number of vendors be involved with trialing the new vendor page format. Then the bugs could have been worked out (like having product description not end up on the 2nd tab, which means they might as well hide the info, given people's short-attention span) and it would also have given vendors time for education as to how the new pages are meant to work.

Just my two cents... no question that the people on this project only want increased sales for vendors, but I'm afraid there's show-stopper issues that are going to prevent that from happening, your own experiences being a prime example, Acadia.
