It would be a good thing to remember that Italy has still not received its 767 tankers, because there are problems with the centerline hose and drogue.

Boeing’s delivery of 767 tanker aircraft to the Italian Air Force has slipped again as the company fixes a problem with the hose-and-drogue refueling system, a senior Italian defense source said.

Italy ordered four tankers in 2002, with deliveries first expected in 2005, before a series of hitches, including vibrations in wing pylons, pushed the schedule back.

One of the reasons that Northrop won the last time around, was that the USAF doubted that Boeing could deliver the tankers on time and on budget.

Also note that drogue/boom thing is an area where Boeing is specifically claiming that its high level of expertise makes them uniquely suited for the contract.
