I'm going solely by what they discussed during the Q&A yesterday. From that, what we now call LMO is really going to be kicked into a significantly higher gear and they plan to make it much easier to inject or remove Express packages into/from the Ground network, including residential overnight. I'll have to rewatch it to get more of the particulars, though something was mentioned about Ground having midday sorts and they went deeper in explaining how it would be determined which Express or Ground facilities would be closed and merged with others.
