You mean they aren't restocking thier Up & Up nighttime underwear??? I know ts been about a year since they quit carrying the Jumbo packs of both the GoodNites and the Up & Up brand pants, so they might be doing one of two things:
*the Up & Up version may very well get the upgrade...
-- OR --
*They are clearing out remaining stock of the Up & Up version to make room on store shelves for the new L & XL size GoodNites in about a month, which is most likely the case...
As a side note, I wonder if places like Target, CVS, Meijer and any other store branded version of the GoodNites will still sold, or if they are all getting updates as well... I guess we'll see shortly after the new sizes are officially unveiled...
