For those asking for a screenshot - here's what this latest test of the new view item page design looks like.
By default, it shows Specifics and you have to navigate to separate tabs for Description and Shipping, returns and payments.
It appears eBay thinks they can technically fulfill their promise to "move item specifics and description above ads modules" in the new design by simply shifting the description over to a new tab.
There are also still the many rows of other items, mostly PL ads, below the feedback module.
Personally, I think this is pretty disingenuous but eBay has kind of painted themselves in a corner on this one - as @my-cottage-books-and-antiques pointed out with recent testing eBay has done with Promoted Listings, having ads as high up on the page as possible likely has a huge impact on conversion (and therefore ad revenue).
Given eBay's extreme focus on increasing ad revenue, they are not likely to accept any design which pushes ads so far down the page that it significantly impacts conversion, which is likely what would happen if they move the ads below and keep the IS and description in one module vertically (especially for items with long descriptions).
This is not an acceptable solution in my opinion, and eBay needs to find a better way to balance their need for ad revenue with the best interests of sellers and the best experience for buyers.
