Express plan is to retain business stops and bleed off as many resis as possible. They are putting a heavy emphasis on overnight service, especially business stops. Business P1's will be 1030, resi P1's will be 1200 (areas that have traditional commit times), which has already launched in some markets. Standard overnight service is likely to change before the end of the year, with business and resi stops both going back to having the same commit time. Express is also moving away from afternoon packages being delivered in the P1 cycle, which is a big reason behind the shift of P1 freight to part-timers.
FedEx expects continued rapid growth in ecommerce and Ground will be a huge part of that. Express won't, at least not on the delivery side. The changes Express is making now are to accommodate more overnight volume and preserve service commitments. They will be doing more to differentiate the Express and Ground brands.
