I have not noticed any changes to my Watch List page.
eBay rarely announces such changes, and often eBay will test pages by rolling out changes in stages, so it is possible you are seeing something new that others are not yet seeing.
Also possible that your browser is dealing with conflicting info from your cached copy of the page and what eBay is trying to deliver. Try holding down the shift key and refreshing the page to bypass your cache if you are using a desktop browser. Or try manually deleting just your eBay cookies once to see if that makes a difference.
