Hey Jan, I beleive that it was mentioned that the downloaded info for cats/subs comes directly from eBay now (as part of the API changes in poster), so if eBay has changed the catagories, it's logical to assume the data would be correct to download.
Of course logic aside... need I say more?
You may have to try the download, even if you don't want to. It may be the only to see if the data has been changed.
